yellowing fans/ red stems not entire sure cuz I thought I gave enough food

Looks like moisture stress..either your running too hot, need to water a bit more often, or need to keep your humidity higher..don't worry about the deficiencies just make sure to run a good amount of water through them and double check temps and humidity they should Perk up but the leaves won't ever change back to green

Sounds good and I have a question. I have high and low temp/hygrometer that is pretty accurate (did some controlled experiments and my temps are pefect with a high of 77tops(dreding the summer temps though) and a low of 65. But my humidity doesn't go past 44 and it usually more like 37-40 I know this is kind of low but what is optimal humidity during flower? If anything I can keep a bucket with water and a fan blowing on it to up the humidity

What is the ph of the water your putting in and what is the ph of that water from the run off? Looks like several problems. It has appearence of nute lock out, over watering and light deprivation. What was your nitrogen feeding like in veg and 2 week of flower before the foods switch?

Unless its an aact I always adjust ph to 6.5 don't usually check run off but I use the soil test tablets now and the then and it comes up fine. I havnt done it in a while though honestly and probably should. I stupidly changed to flower nutes as soon as I switched over. Didnt add additional N till I saw signs of what I thought were defficiency. There under a 600w at like 16" above them along with a 65w big floro for some added spectrum and 3 additional 26w floros under the canopy so I don't think thier light deprived

I want to clarify I said don't worry about the deficiencies because it seems like you have that in check already..the humidity should be about 55 to 60 in veg and about 50 in flower however make sure you have air exchange later in flower don't want any mold..some people like a lower humidity I do not because with high heat and low humidity people don't realize they are negatively affecting the plant..the last couple days of flower I've heard its good to run a dehu and bring humidity low as possible supposedly this adds frostiness, going to give it a try next time coupled with a 48 hour dark pd

Sounds good!! I think I'm heading in the rite direction. I deff need to up my humidity though temps are on point. I just messed up in my feed schedule. Live and learn as theu say and hey. I'm happy with how they look. At thier age, size is deff better theny last round. And they smell amazing. Its like walking into a room of every exotic fruit u could think of. Its blackjack by the way. What are you, running this round?

And thanks by the way. U have earned a fellow growers respect!

What you can do is get yourself a mister from a pet store..they have very fine settings its a pump mister and green top that is what your looking for..that will keep your humidity at a better level just do not saturate buds and try to most under the canopy

Np at all! I'm not growing anything right now ofcourse ..might have something to post soon though

Bugs were mentioned once. That's why I go hydro. Have you ever had aphids? Holy crap that sux. I had a bug that bred in the roots, and the larvae ate the roots of my clones. Fat little maggots. That came from some gardening equipment being stored too close to my cloning setup. Live and learn. In terms of bugs: If you don't understand them, and there is a problem, kill them all. If it's in soil, get lacewings or ladybugs, do it fast. Some of those leaves may be saved. I think something is eating nutes at the root level and the plants are drawing down from the leaves. By the way, the purple is an oxygen deficiency. Cold interferes with a plant's ability to uptake O2. Its all relative. Maybe the sativa wants tropical temps. Good luck, brother.
