4° DWC Gorilla Cookies FF

hey buddy, first of all - nice grow so far. You can check several things: - environmental conditions (definitely heat stress as well - curling leaves and pointing upwards) - not pointing fan at plant and maybe lower light for a few days that plants can recover or put it further away. - ph/ec maybe u got little nutrients lockout - Potassium Deficiency (burned leave tip/edges and yellowing in margins But I would say in your case it started with Potassium Deficiency and got some heat stress as well on top. So I would suggest flush it once - adjust ph/ec and get new nutes inside or just add Potassium and lower lights for a few days. they will recover for sure. if you got further questions just DM me :) Good Luck buddy

I agree with some of the guys, that it is an early sign of fading, which would make sense a t this stage, or she could want more nitrogen, not sure though of the composition of your nutes. I would bet on the first one though, the orange bud just recently finished and she started to fade very similar to yours. Also looking at the age of your plant and her expected flowering time, she should be ok to start fading.
