Yellowing… why, N, maybe Mag….😭

Week 5 liming the medium then add a whole slew of other organics to your medium, wondering why there are symptoms. You have 0 control of your mediums pH. The rate of release of dolomitic lime is pH-based making it unpredictable, you have organic nitrogen going to work via nitrification, alot of reactions going on, more reactions a medium has the higher the temp, if it goes under 67f or over 75f uptake can get messed up in unexpected ways . Hard to pin point with so much going on. 😕 I think after adding so much ammendments, probably should not add more to what looks like a skewed ratio of nutrients causing a pH imbalance. Most likely from all the excess nitrogen in nh4+ form causing the acidic skew, at 6.2 there will be almost no nitrogen conversion to nitrates. Ammonium NH4+ is the conjugate acid of ammonia NH3 and can release a proton in water, a process that creates an acidic environment. Ph skew. The excess H+ ions can lead to a depletion of other essential cations like calcium magnesium and potassium from plant roots and soil. That's why your plant is presenting symptoms you see.

Nah man, 24h is fine, it looks more K excess and Ca, N,Mg lock P.s. if u,re using 24h u,d water twice as much Keep the soil moist and stop giving K for a week. Or flush and feed anew

N tox. 24/0 bad 18/6 good m0use has given you good advice.

Hey there it’s just simple lack of nitrogen if leaves get light color early flower your lacking ni

Looks like your asking too much from your plant.. Cake them in nutes and light is only half the story. Roots, environmental factors and co2 adds another few problems to get over.. You are trying to force feed a fat pig...

Doubt it has any issues to do with Nitrogen in a deficiency especially if your using Gaia Green, that stuff almost always gives me N tox. Your week 6 looks like it has to much N and week 7 is showing the discoloration. Leaning towards light and maybe a small issue with Mg but not the main cause. I read your giving them 24/0 lighting to get a good DLI.... you can get a "good" DLI from less hours on its all about intensity over time. Eg. you can have a DLI of 40 over 12hrs or 24hrs and its the same thing. I would be dropping your plants down to a 18/6 schedule or even a 16/8 with around 35-40 DLI. your light is 600W and can totally handle it. the plants can't utilize much more then this without supplemental CO2, this number is based off of research from DR. Bruce Bugbee. A cannabis researcher from the Utah State University, they know their shit, more then most of us on this site. You quote PPFD in your diary, if your using photone app to calculate this, know its not accurate but it is replaceable. eg. its not the true PPF but it will show you the same number even if its not true. Better to go off of some of the manufactures light maps and then adjust from there based on the growth. To tight, to much light, to loose not enough. Your earlier weeks were talking about node spacing being to tight. Sign of to much light. Use that dim function to its full potential. Mg does not need to be high dose either. Can sprinkle in a bit of epsom salts if need be. eg magnesium sulfate. When I have used Gaia in the past I find it needs a bit of a Mg boost every few weeks. and with out it. my plants look a bit pale. Its not a perfect product but it does well for what it is. but fix your photoperiod eg 24/0 as thats not helpng and plants need downtime.
