Hoping some of you can recognize and help
Opened the tent today at lights on to see leaves curling to the point of twisting.
Yesterday was the first day of Advanced Nutrients Overdrive after a few days of pk booster, and the dehumidifier didn't run overnight, those are the only two variables that changed.
I run at high temps, 86 degrees and 65% rh with 1400ppm co2 as recommended by Floraflex, and they have been cruising for 6 weeks in the environment with no issues before today. Grown in Rockwool, fed a fresh res of advanced nutrients till waste drain daily.
