started grow question 4y ago
Hi all. Just a quick one. Do I need to use calmag on every watering using a sf4000. It's my first time using a led. Thanks for any advice. 👍🏻👍🏻

Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

Help with lockout of deficiencies. Don’t know what to do from here I already flushed em but doesn’t seem they uptake anymore
Neut lockout/Deficiency? I was watering less more frequently in fabric pots. I believe it created a lockout in the 3 taller plants by not allowing more run off of water. Correct me if I’m wrong there but what do I do now? They are not looking well and now the leaves are curling

Calcium deficiency impossible to fix.
I cannot get ahead of calcium deficiency in spite of adding calcium nitrate base with extra cal-mag daily. I just keeps getting worse and worse... any advice? Hydroponic RDWC, day 29 flower. It’s fine in veg, once they hit bloom, can’t keep them healthy.

Potassium deficiency?
Can you confirm this is a potassium deficiency? This happened after a flush of an amended soil (SoHum), please take into account before you answer. I do have some Down to Earth Organic White Azomite Powder OTW, just not sure how much to add yet.

Nitrogen toxicity? Deficiency? Something else? Stumped!
I don't get it. Is this N toxicity? Serrated upturned edges, clawing, slow growth. But how? FFHF 75% FFOF 25%. Just Cal-Mag water. No food. NLS in bottom 3rd of pot. Not wind burn. Not too hot/dry at all. N deficiency? Yellow leaves on first bottom two only. I'm stumped.

Cal-mag deficiency?
Hi guys, I think it's magnesium deficiency (early flowering). I have also noticed a few small burnt spots on the leaves. Is this time for cal-mag? Or am I reading this wrong?

Overfert?
I'm following the biobizz fertilizers schedule and watering the plant with 1/1,5 l every 4/5 days. Some tips of the leaves are yellow. Do I need to worry? How should I handle the situation?

need exact details on making DIY egg shell fert, (how many eggs per how much water, dilute ratios, effective dose etc, using minimal eggs and vinegar.)
How many egg shells do I need to make an effective CAL fert? Are 6 shells soaked in 500ml of water with 1tsp of vinegar enough? What about if I boiled them in plain water? What is the dosage, ratio, and minimum amount of vinegar to use for this process, so it doesn't smell

Friends need your help! the leaves turn yellow at the seedling stage!
Friends, help me figure it out! First I will describe my conditions! - Tap water 110 ppm - LED QB288 Rspec 250 Watt light works at half the power! - Advanced Nutrients three-component Fertilizers Micro Grow Bloom now I'll tell you how it was! after they have sprouted! they were planted in the system! I made the solution on the recommendation of the fertilizer manufacturer! I added 1 ml/l of each component and it turned out 410 ppm! The second week I changed the solution completely and added 2 ml/l of each component, it turned out 600 ppm the yellowness on the leaves appeared after the first week! I thought it was a magnesium or iron deficiency! and I changed the solution and added 2 ml / l of fertilizers! I keep the ph of the solution within 5.7-6.0 drip irrigation works constantly! The temperature in the box is 23-25 C - humidity is 40-60% Inside, there is a fan on top that turns 360 degrees to blow the plants!
