Hi guys so I’m about to be coming into week 7 of flower on my GG4’s. For some reason I have two plants out of 8 that are showing signs of what appears to be heat stress. If it is heat stress I don’t know why it’s happening now. They were stellar all the way up to this point. Then temp for the first few weeks of flower was about 78-80 with absolutely no signs of stress. Now my temps are like 68-75 RH 38-50. And a few seem unhappy. Lights are 1000w DE about 3 feet above canopy maybe a little less. Now before you say “it’s the lights” just know they were picture perfect happy under full power until this point.
I’m feeding like 6 times a day in 15-20 second intervals @650ppm. They are in 5 gallon pots of coco/perlite and runoff is in check. Can anyone tell me why plants would do this other than heat stress. I turned down fans that were near these and dimmed lights to 750w. Also note that recently I bumped c02 from about 600 to 1200 ppm. Other plants seem happy. Any input would be very helpful. I know it maybe too late to affect any real change but would like to get it figured out for next time. Thanks for getting this far!
