They don't look bad to me. When I first 'flip' my plants, they go through a period of new pale growth as they stretch. Some growers actually keep going on the grow nutes for the first week of flower for that exact reason!
Keep your temps under control however you can; if 90 is as high as it ever gets, and you can guarantee that, consider adding a CO2 tank to your grow and allow the plants to take advantage of that. You certainly have enough light, and your plants look healthy enough to take it.
stinkyattic Reviewed by stinkyattic on . All very new growth yellow. Ok a couple things happened all at once so not sure what might have happened if anything. Plants were all doing good under 1000w metal halide. Was watering every couple days every other water 1/2 nutes of fox farm grow big. Plants are in fox farm ocean. So about 4 days ago I gave a first full strength feeding and then about 2 days ago I gave straight water everything was looking good. I ph the water after adding in nutes and its always between 6.0 to 7.0 generally around 6.5. Plants Rating: 5
