I did not want to finish this grove so early, but I thought about it well and decided that it was enough to torment this bush, I found a problem in highlighting at night (6 hours) And fertilizer is not real from GHE, in my country they make fake unfortunately, you need to buy from official dealers! And Bubba Kush 2.0 gained very good THC!

It's been an interesting week. I had to ask for help with resolving the intense smell coming from my garden... I can smell it from my driveway at this point.. I was advised that I probably turned my fan up way too high, which overloads the carbon filter on the end of my exhaust. I ordered another new one.. turned it down.. and I also had to cut down the cheese auto... all her trichomes were cloudy bit I definatly could have left her for another week... just couldn't handle the smell lol. Ask for help and you shall receive, thanks Growdiaries. And thank you Oozlefinch for the solid advise.. ✌️ I bought a rosin press this week and it's awesome.. she will be used for this grow as soon as things are ready. I cut out my backyard to plan for round #3 for all these plants.. plus a whole lot more! Process/ Environment changes: -Turned down my exhaust fan.. the carbon filter can't keep up with the amount of air being pushed through it.. in the water industry we would call this 'short circuiting'.... The Gorilla cookies is growing well. It's a tall plant with long nugs ( I hope the full out a lot more). I would recommend supporting the branches at this point in the grow. There's a slight smell coming off her and trichome production was late to start compared to most the other plants I have... I suspect she will go past 90 days unfortunately, but I'm excited to see what the finished product looks like. Hitting her with compost teas at a pH of around 6.7 That's it.. I'm on auto pilot at this point.. there's not much I can do except sit back and wait. Thank you Fastbuds

Eccoci qui... Tutto va per il meglio, questa settimana non ho applicato stress alla piccola, ma ho guardato l'evoluzione che ha avuto dando i nutrienti. Ora ha un odore davvero intenso ed uno strato di resina pauroso, vediamo come si riprende dalla defogliazione che ho fatto settimana scorsa. Seguiranno aggiornamenti, grazie a tutti per il supporto🔥🌲❤️

End off week 11, concluding week 7 off flowering: Hi(gh) Guys! Thanks for viewing my weekly update (i hope again?)! The girls are doing great. I have to come back on a previous statement, i said that 3 girls are ahead of the rest and up for an early harvest, although that is both true, actually there straight on schedule, and i think the rest is behind. The manual on this strain says they need 9 weeks and flowering week 7 is now concluded. They start to gain weight all three and the stems are beginning to bend. This upcoming week they will get their last nutrients, but week 9 they will only get water, so i can flush properly for the upcoming week and a half. End of week 9 they will be terminated, because my vaporizer is idle for too long already! As for the rest, they will need at least 2 or 3 weeks longer, because everywhere i look i see loads of white hairs, and i’m seeing forward to show you some off my biggest nugs ever! This is my first time on this website and i’m having a lot of fun. Earlier i'd grow my best round ever with 9 Gorilla Glue #4 ladieboys, what nice buds did they produce. But i guess the OG is going to be at least as close. That’s good for me because this is my favorite strain. Please leave a comment, and like my post. My account needs a little more love! Please come and see for another update next week. (p.s. sorry for that shakie video, I was sitting on top of an little pebble with my knee, but I liked the video anyway…)

Oh man I messed up by not cutting candy kush #3 before the rain last week and lost a little less than half to botrytis 😓😓😞 but can only be mad at myself for not chopping her down sooner and I will still end up with a few ozs from CKE #3. Candy kush #2 just exploded with trichomes and orange pistils over the last 8 days so I'm very glad I left #1 & #2 out,going to chop #2 today or maybe tomorrow if it stays warm and sunny!!! Candy kush #1 is the biggest of the 3(makes sense since I put her in a full 15 gallon grow bag). When I chopped #3 last week cke #1 was no where near done but now almost all her pistils have turned brown and she has milky trichomes all over!! Im the most excited for CKE #2 ,she smells like the old school west coast og kush with a hint of chem to her it's amazing!! Candy kush #1 got more of the sweet special traits in the nose smells very sweet and earthy but im sure both will be amazing smoke no doubt in my mind!! ✌️ ☮️

The temperatures, humidity, height, and watering volume(if measured) in grow conditions are all averaged for the week. The pH is soil pH. Any watering done by me is well water which is 7.6 pH and 50° F. Any listed nutrients are ml/gallon of soil spread evenly across the top of the soil. Day 1 we had a high temperature of 77°F. I watered 4-5 gallons per pot once. Day 2 we had a high temperature of 81°F with partly cloudy skies. We missed the 50% chance of rain today. I watered 4-5 gallons per pot, once. Day 3 we had a high temperature of 71°F with cloudy overcast skies. It's rained most of the morning with more rain in the forecast. Day 4 we had a high temperature of 77°F. We had a big front move through today. It been raining and overcast all day. The girls seem to be loving it, but I'll need to treat for powdery mildew again ASAP. Day 5 we had a high temperature today of 83° F. Skies were cloudy to partly cloudy and it rained for several hours. Day 6 we had a high temperature of 91°F. We had rain overnight and early morning. The skies were partly cloudy and I didn't have to water today. Day 7 we had a high temperature of 90°F. Skies were sunny and I watered 4-5 gallons per pot once. I treated with Growers Ally Fungicide just before dark. This week was a success. We had lots of rain and cool temperatures. The powdery mildew flared up a little as I didn't treat because of the daily rain. We finished our The week with warmer temps and sunshine. The girls have slowed down their upward growth and have almost transitioned to generative phase one or flower. They're starting to smell citrusy.

Man, it's been a crazy week. These past few days have been brutal – seriously cold with this crazy humidity. I don't know about you, but I'm sick of the chills and the way my skin feels all sticky. It's been a struggle, but I'm finally getting on top of things. I think I've figured out a good routine to dry things out around here, so hopefully, I'll be feeling a lot more comfortable soon. It's been interesting watching these permanent marker plants grow. One of them is still kinda lagging behind, but I think I've got the other one figured out. It's stacked so perfectly, and it's starting to look super sparkly, almost like it's got little crystals on it. I'm curious to see if the other plant will catch up.

Buds are really starting to put on weight I was a little nervous because I have never grown autoflowers before and to I have never done low-stress training before so far everything has worked out magnificently minus the pH that was off and the temperature drop elsewise these plants are all significantly larger than originally anticipated

Day 45-52 (Day 46) I just realized I forgot to zip up a small flap in the tent for at least 5 days or so. This probably made the added co2 useless. All the plants are slightly clawing and almost look overwatered, which is normal for plant at this stage but I wonder if the lower co2 levels are contributing at all. I couldn’t help myself today and did a small defoliation. Hopefully this doesn’t stress them out too much. I took about 15-20 leaves per plant. I really want some of this larf on the bottom fill out more. Even by 10-15%. (Day 47) Wow. I just noticed that #5 is putting on a thick layer of late frost. I’m guessing this has to do with all the mid flower feedings. Unfortunately the density on this girl lacking big time. Especially on the lowers. This could be genetic but there is too many variables at play to say for sure. If this stuff smokes proper I will continue to feed in mid flower. Plants are really starting to fade out here now. #3 in particular has some odd red coloring in a few of the leaves. (Day 48) I watered in 2 gallons on each plant making sure to get some decent runoff from each. Sucks that #3 didn’t fill out. The genetic potential was definitely there, something just went awry after that tea I gave it. I have at least 2 or 3 clones of that I will try outdoors. It’s been a very P hungry plant too. The stems were purpling like crazy, even in veg. Some people say this can be fixed with a microbial product like Mammoth P or Tribus which I might try for my next grow. #6 isn’t really filling out much either unfortunately. Tops look decent but everything under that is pretty leafy and airy. #1 and #7 are the clear winners here. #1 especially is picture perfect. If I wasn’t working on another project after this I would clone just #1 and run another scrog like this from clone. (Day 50) I was plucking some leaves today and I found a confirmed banana sticking out of one of the main colas on the stubby pheno. I didn’t defoliate this one too much so I wonder if it was caused by stress at all. I hope I don’t find anymore because we only have 10 days left here. (Day 52) My family member trimmed up the m39. It looks super scraggly but has some decent crystal nonetheless. That’s partly why I would never use an amazon blurple for flowering. It just doesn’t have the same canopy penetration that a light like mine does. Although for a budget setup they’re pretty awesome.

Yellow butterfly came to see me the other day; that was nice. Starting to show signs of stress on the odd leaf, localized isolated blips, blemishes, who said growing up was going to be easy! Smaller leaves have less surface area for stomata to occupy, so the stomata are packed more densely to maintain adequate gas exchange. Smaller leaves might have higher stomatal density to compensate for their smaller size, potentially maximizing carbon uptake and minimizing water loss. Environmental conditions like light intensity and water availability can influence stomatal density, and these factors can affect leaf size as well. Leaf development involves cell division and expansion, and stomatal differentiation is sensitive to these processes. In essence, the smaller leaf size can lead to a higher stomatal density due to the constraints of available space and the need to optimize gas exchange for photosynthesis and transpiration. In the long term, UV-B radiation can lead to more complex changes in stomatal morphology, including effects on both stomatal density and size, potentially impacting carbon sequestration and water use. In essence, UV-B can be a double-edged sword for stomata: It can induce stomatal closure and potentially reduce stomatal size, but it may also trigger an increase in stomatal density as a compensatory mechanism. It is generally more efficient for gas exchange to have smaller leaves with a higher stomatal density, rather than large leaves with lower stomatal density. This is because smaller stomata can facilitate faster gas exchange due to shorter diffusion pathways, even though they may have the same total pore area as fewer, larger stomata. Leaf size tends to decrease in colder climates to reduce heat loss, while larger leaves are more common in warmer, humid environments. Plants in arid regions often develop smaller leaves with a thicker cuticle and/or hairs to minimize water loss through transpiration. Conversely, plants in wet environments may have larger leaves and drip tips to facilitate water runoff. Leaf size and shape can vary based on light availability. For example, leaves in shaded areas may be larger and thinner to maximize light absorption. Leaf mass per area (LMA) can be higher in stressful environments with limited nutrients, indicating a greater investment in structural components for protection and critical resource conservation. Wind speed, humidity, and soil conditions can also influence leaf morphology, leading to variations in leaf shape, size, and surface characteristics. Small leaves: Reduce water loss in arid or cold climates. Environmental conditions significantly affect gene expression in plants. Plants are sessile organisms, meaning they cannot move to escape unfavorable conditions, so they rely on gene expression to adapt to their surroundings. Environmental factors like light, temperature, water, and nutrient availability can trigger changes in gene expression, allowing plants to respond to and survive in diverse environments. Depending on the environment a young seedling encounters, the developmental program following seed germination could be skotomorphogenesis in the dark or photomorphogenesis in the light. Light signals are interpreted by a repertoire of photoreceptors followed by sophisticated gene expression networks, eventually resulting in developmental changes. The expression and functions of photoreceptors and key signaling molecules are highly coordinated and regulated at multiple levels of the central dogma in molecular biology. Light activates gene expression through the actions of positive transcriptional regulators and the relaxation of chromatin by histone acetylation. Small regulatory RNAs help attenuate the expression of light-responsive genes. Alternative splicing, protein phosphorylation/dephosphorylation, the formation of diverse transcriptional complexes, and selective protein degradation all contribute to proteome diversity and change the functions of individual proteins. Photomorphogenesis, the light-driven developmental changes in plants, significantly impacts gene expression. It involves a cascade of events where light signals, perceived by photoreceptors, trigger changes in gene expression patterns, ultimately leading to the development of a plant in response to its light environment. Genes are expressed, not dictated! While having the potential to encode proteins, genes are not automatically and constantly active. Instead, their expression (the process of turning them into proteins) is carefully regulated by the cell, responding to internal and external signals. This means that genes can be "turned on" or "turned off," and the level of expression can be adjusted, depending on the cell's needs and the surrounding environment. In plants, genes are not simply "on" or "off" but rather their expression is carefully regulated based on various factors, including the cell type, developmental stage, and environmental conditions. This means that while all cells in a plant contain the same genetic information (the same genes), different cells will express different subsets of those genes at different times. This regulation is crucial for the proper functioning and development of the plant. When a green plant is exposed to red light, much of the red light is absorbed, but some is also reflected back. The reflected red light, along with any blue light reflected from other parts of the plant, can be perceived by our eyes as purple. Carotenoids absorb light in blue-green region of the visible spectrum, complementing chlorophyll's absorption in the red region. They safeguard the photosynthetic machinery from excessive light by activating singlet oxygen, an oxidant formed during photosynthesis. Carotenoids also quench triplet chlorophyll, which can negatively affect photosynthesis, and scavenge reactive oxygen species (ROS) that can damage cellular proteins. Additionally, carotenoid derivatives signal plant development and responses to environmental cues. They serve as precursors for the biosynthesis of phytohormones such as abscisic acid () and strigolactones (SLs). These pigments are responsible for the orange, red, and yellow hues of fruits and vegetables, while acting as free scavengers to protect plants during photosynthesis. Singlet oxygen (¹O₂) is an electronically excited state of molecular oxygen (O₂). Singlet oxygen is produced as a byproduct during photosynthesis, primarily within the photosystem II (PSII) reaction center and light-harvesting antenna complex. This occurs when excess energy from excited chlorophyll molecules is transferred to molecular oxygen. While singlet oxygen can cause oxidative damage, plants have mechanisms to manage its production and mitigate its harmful effects. Singlet oxygen (¹O₂) is considered a reactive oxygen species (ROS). It's a form of oxygen with higher energy and reactivity compared to the more common triplet oxygen found in its ground state. Singlet oxygen is generated both in biological systems, such as during photosynthesis in plants, and in cellular processes, and through chemical and photochemical reactions. While singlet oxygen is a ROS, it's important to note that it differs from other ROS like superoxide (O₂⁻), hydrogen peroxide (H₂O₂), and hydroxyl radicals (OH) in its formation, reactivity, and specific biological roles. Non-photochemical quenching (NPQ) protects plants from damage caused by reactive oxygen species (ROS) by dissipating excess light energy as heat. This process reduces the overexcitation of photosynthetic pigments, which can lead to the production of ROS, thus mitigating the potential for photodamage. Zeaxanthin, a carotenoid pigment, plays a crucial role in photoprotection in plants by both enhancing non-photochemical quenching (NPQ) and scavenging reactive oxygen species (ROS). In high-light conditions, zeaxanthin is synthesized from violaxanthin through the xanthophyll cycle, and this zeaxanthin then facilitates heat dissipation of excess light energy (NPQ) and quenches harmful ROS. The Issue of Singlet Oxygen!! ROS Formation: Blue light, with its higher energy photons, can promote the formation of reactive oxygen species (ROS), including singlet oxygen, within the plant. Potential Damage: High levels of ROS can damage cellular components, including proteins, lipids, and DNA, potentially impacting plant health and productivity. Balancing Act: A balanced spectrum of light, including both blue and red light, is crucial for mitigating the harmful effects of excessive blue light and promoting optimal plant growth and stress tolerance. The Importance of Red Light: Red light (especially far-red) can help to mitigate the negative effects of excessive blue light by: Balancing the Photoreceptor Response: Red light can influence the activity of photoreceptors like phytochrome, which are involved in regulating plant responses to different light wavelengths. Enhancing Antioxidant Production: Red and blue light can stimulate the production of antioxidants, which help to neutralize ROS and protect the plant from oxidative damage. Optimizing Photosynthesis: Red light is efficiently used in photosynthesis, and its combination with blue light can lead to increased photosynthetic efficiency and biomass production. In controlled environments like greenhouses and vertical farms, optimizing the ratio of blue and red light is a key strategy for promoting healthy plant growth and yield. Understanding the interplay between blue light signaling, ROS production, and antioxidant defense mechanisms can inform breeding programs and biotechnological interventions aimed at improving plant stress resistance. In summary, while blue light is essential for plant development and photosynthesis, it's crucial to balance it with other light wavelengths, particularly red light, to prevent excessive ROS formation and promote overall plant health. Oxidative damage in plants occurs when there's an imbalance between the production of reactive oxygen species (ROS) and the plant's ability to neutralize them, leading to cellular damage. This imbalance, known as oxidative stress, can result from various environmental stressors, affecting plant growth, development, and overall productivity. Causes of Oxidative Damage: Abiotic stresses: These include extreme temperatures (heat and cold), drought, salinity, heavy metal toxicity, and excessive light. Biotic stresses: Pathogen attacks and insect infestations can also trigger oxidative stress. Metabolic processes: Normal cellular activities, particularly in chloroplasts, mitochondria, and peroxisomes, can generate ROS as byproducts. Certain chlorophyll biosynthesis intermediates can produce singlet oxygen (1O2), a potent ROS, leading to oxidative damage. ROS can damage lipids (lipid peroxidation), proteins, carbohydrates, and nucleic acids (DNA). Oxidative stress can compromise the integrity of cell membranes, affecting their function and permeability. Oxidative damage can interfere with essential cellular functions, including photosynthesis, respiration, and signal transduction. In severe cases, oxidative stress can trigger programmed cell death (apoptosis). Oxidative damage can lead to stunted growth, reduced biomass, and lower crop yields. Plants have evolved intricate antioxidant defense systems to counteract oxidative stress. These include: Enzymes like superoxide dismutase (SOD), catalase (CAT), and various peroxidases scavenge ROS and neutralize their damaging effects. Antioxidant molecules like glutathione, ascorbic acid (vitamin C), C60 fullerene, and carotenoids directly neutralize ROS. Developing plant varieties with gene expression focused on enhanced antioxidant capacity and stress tolerance is crucial. Optimizing irrigation, fertilization, and other management practices can help minimize stress and oxidative damage. Applying antioxidant compounds or elicitors can help plants cope with oxidative stress. Introducing genes for enhanced antioxidant enzymes or stress-related proteins over generations. Phytohormones, also known as plant hormones, are a group of naturally occurring organic compounds that regulate plant growth, development, and various physiological processes. The five major classes of phytohormones are: auxins, gibberellins, cytokinins, ethylene, and abscisic acid. In addition to these, other phytohormones like brassinosteroids, jasmonates, and salicylates also play significant roles. Here's a breakdown of the key phytohormones: Auxins: Primarily involved in cell elongation, root initiation, and apical dominance. Gibberellins: Promote stem elongation, seed germination, and flowering. Cytokinins: Stimulate cell division and differentiation, and delay leaf senescence. Ethylene: Regulates fruit ripening, leaf abscission, and senescence. Abscisic acid (ABA): Plays a role in seed dormancy, stomatal closure, and stress responses. Brassinosteroids: Involved in cell elongation, division, and stress responses. Jasmonates: Regulate plant defense against pathogens and herbivores, as well as other processes. Salicylic acid: Plays a role in plant defense against pathogens. 1. Red and Far-Red Light (Phytochromes): Red light: Primarily activates the phytochrome system, converting it to its active form (Pfr), which promotes processes like stem elongation and flowering. Far-red light: Inhibits the phytochrome system by converting the active Pfr form back to the inactive Pr form. This can trigger shade avoidance responses and inhibit germination. Phytohormones: Red and far-red light regulate phytohormones like auxin and gibberellins, which are involved in stem elongation and other growth processes. 2. Blue Light (Cryptochromes and Phototropins): Blue light: Activates cryptochromes and phototropins, which are involved in various processes like stomatal opening, seedling de-etiolation, and phototropism (growth towards light). Phytohormones: Blue light affects auxin levels, influencing stem growth, and also impacts other phytohormones involved in these processes. Example: Blue light can promote vegetative growth and can interact with red light to promote flowering. 3. UV-B Light (UV-B Receptors): UV-B light: Perceived by UVR8 receptors, it can affect plant growth and development and has roles in stress responses, like UV protection. Phytohormones: UV-B light can influence phytohormones involved in stress responses, potentially affecting growth and development. 4. Other Colors: Green light: Plants are generally less sensitive to green light, as chlorophyll reflects it. Other wavelengths: While less studied, other wavelengths can also influence plant growth and development through interactions with different photoreceptors and phytohormones. Key Points: Cross-Signaling: Plants often experience a mix of light wavelengths, leading to complex interactions between different photoreceptors and phytohormones. Species Variability: The precise effects of light color on phytohormones can vary between different plant species. Hormonal Interactions: Phytohormones don't act in isolation; their interactions and interplay with other phytohormones and environmental signals are critical for plant responses. The spectral ratio of light (the composition of different colors of light) significantly influences a plant's hormonal balance. Different wavelengths of light are perceived by specific photoreceptors in plants, which in turn regulate the production and activity of various plant hormones (phytohormones). These hormones then control a wide range of developmental processes.
