Question for Pro's about feeding

This questions seems below you on how your replies are in other questions. Confused why your even asking it?

Just noticed it's a huge bucket with little to no oxygen getting into said bucket. Entire growth will be limited by lack of oxygen. No point in 18 hours of cellular respiration without the oxygen to support it. Just gonna start anerobic fermentation after a couple hours of night. Need to have oxygen diffuse in and out of that pot, in nature this would be mimicking high and low pressure fronts. Indoors we replicate with negative pressure linked to rh overnight. Without doing so your plant will most likely jist turn yellow and sick around week 3-4 once all the radicals accumulate from anerobic fermentation in a bucket full of soil with very limited oxygen. Microorganisms accelerate drastically during flower, micros compete with plant for oxygen during critical time. 40% of all carbon your plant captures exudes through the roots as sugars to feed micros. If you do not diffuse the carbon out the soil it slowly begins to increase moisture retention of soil. In a bucket that's a death sentence Indoors. Nothing good ever happens in a medium that cannot breathe. No such thing as too much water in a medium, only a medium that retains too much for too long.

Nice John, love a little experimentation. Those 6 hours of light are going to be extreme ppfd to meet dli. Love it. ❤️ What I like to do is measure the ec of the soil. The more nutrients a plant uses the more ec drops. Once it gets low you add ppm raising ec. Then you only have to worry about balancing the ratio we call ph. Nutrient uptake is not a day or night process. When daytime transpiration is active the plant can use the flow of water to provide "free" uptake so to speak. When there is no transpiration the plant t needs to use atp to uptake nutrients through active uptake which requires atp. During those 6 hours get your dli as high as you can. For those 18 hours of night you cannot let your rh sit above 55 for 18 hours without some form of evaporation, moisture will quickly take hold and stagnate in medium that only performs transpiration 6 hours. Cellular respiration is primarily li led to temps so before trichomes appear don't be afraid to let temps rise a little at night. Will go a long way to producing much more energy that can be used for much more growth. 60 dli is 60 dli whether you capture it in 6 hours or 18. 90% of all atp comes from cellular respiration not photosynthesis. Photosynthesis is just carbon capture and hydrogen scavenging and 10% atp. Best of luck John 👍 look forward to seeing some beasts.

Its looking good. Turn it turn 18hrs on 6 off. You shouldnt really give them any less than 12hrs at any stage but autoflowers prefer more light and you will find most "pro" gardeners do 18/6 or 20/4.

18/ 6 veg stage 12/12 flowering stage Just Keep it simple is the easiest way

ppm is a concentration. it's 3500ppm in 1L or 1 gallon, regardless, not trying to be a dick. better to know than repeatedly type it that way, imo. If giving the same DLI over 6 hours i'd feed it as you have or would normally do entering flower -- assumes the plant is not damaged by ~1800PPFD to reach 35-40 DLI over 6 hours, about which i have significant doubts. Plants adapt to the level of light they receive per hour or per second (rate being key). It impacts concentration of chloroplasts in leaf surface etc... So a plant adapted to ~600ppfd over 18 hours isn't necessarily going to work well at ~1800ppfd over 6 hours. This is same cause to effect why an indoor plant taken outside often suffers in direct sunlight. I'm not certain it'll cause light damage, but it's at minimum borderline. When i lost power and moved a plant outside in direct sun... it wilted and had interveinal damage withink 3-4 hours, bwahah. Probably a bit more than 1800ppfd on the plant from all angles, top-to-bottom though and not just accross the canopy with artificial light. If you are giving less DLI over 2 weeks, you should reduce your feed... start with a proportional change relative to change in DLI then observe and adjust. If giving 1/3rd DLI compared to before, i'd drop to 1/3rd dose of what you gave before. I would do this starting the irrigation before you start 6/18. Observe and adjust... next time you do it, it can be a smooth transition. There's no need to go to 6/18. 12/12 is plenty for the hormone to build up and cause a response by the plant. Think of how quickly a re-vege can be caused... a few minutes of light is enough to flip the switch back to vege phase even 6 weeks deep into flower. The hormone levels clearly cause a nearly immediate reaction. Just one night it doesn't create enough, it re-veges. You don't realize it's in flower for nearly a week before your eyesight is good enough to discern something. It's in flower several days before you see a nub of a preflower with a scope. (that is simplified / watered-down -- preflowers can show up in an extended vege phase... conceptually communicates the idea, though... That there is a delay between biological processes changing and being detectable by human senses.) So, there's very little time to be saved, even if it does have an effect on transition to flower and lots of negatives related to drastic change in light intensity or depriving it of DLI, depending on the path you took. Lots of potential and likely negatives with minimal benefit possible. Plus, anything that potentially shortens flower phase also will reduce yield. The plant isn't going to compensate growth rate.. if it finishes sooner than 'control group', it'll be a smaller plant. Not saying it will be shorter due to 6/18, but i am assuming that's the goal? quicker transition, faster flower? unless it also stimulates a faster growth rate (seemingly no cause for that effect), it inevitably has to result in a smaller yield, too. So, any time benefit is mitigated by a loss of productivity and averages out the same over time or less. There may be some contexts where it's a benefit in regard to logistics only, but it'd be very specific and limited situations. Have fun experimenting if heart is set on it, but very unlikely to be a benefit based on existing knowledge base. you'd need to compare clones and accont for any seasonal differences.. easy to confuse growth rate changes, otherwise. too volatile if the temp, rh and co2 levels aren't tightly controlled. The reduced dli for 2 weeks will definitely have a negative impact on results compared to 'control group,' though. That effect alone would be incredibly difficult to overcome for a net-positive.
