I just switch all my 3 1000watts hps
For cob in mid flowering and my planf are lot more yellow than im use to .

Do i have to up my ammendment . And top feed more on my next grow cant figure out all big fan leaf just yellow fast.
50 000 lux is a lot off light .
Or is because of the lower temperature
26 celcius the door close is kind off hot
50% rh i buy smaller dinamable 200cfm fan to be able to keep my heat and humidity higher .
What do you guys think

I can't answer all your questions, but I can tell you that 28°C would be better.

maybe turn down the lighting until the plants catch up.

Sounds like too much light, too fast for your plants. Try raising/dimming the light slightly. Led spectrum is more powerfull to a plant than hps, increased photosynthesis require more nutrients but its hard to forcefeed the nutrients when the plant is geared towards working under HPS. Less light and next run wou may wanna baby your plants a bit until you are sure by how they react that they can take it.
