Check it out guys, i notticed a little yellowing in the leaves on a few plants before i transplanted, my guess is that it is heat stress from a couple days of being a little too close to the 1000, i have since raised the lights and they are more spread out now, but just want to make sure it isnt something else! feeding 6/9 Rez ph 5.5 runoff is 760 ppm (1.5 EC) Also Ive been running co2 in the sealed room with RH 60% and temps about 80-85, i dropped the temps to 76 anyone want to chime in?
Keep the temps high when using co2. Ninety degrees is ok. They look fine, might be a little fert burn.
