Only thing I can think of is the temp may be too high?

79f really i thought that was a decent temp, and it never goes over 82f and with the light off it stays right around 70f with my ceramic heater w/ thermostat, and i have 2 fans, one blowing down on the plants and one blowing across the top of them, hmmm not sure...

my plants also did this two times i think they react odly when you water them have they straightened out yet cause mine did like a day after both times

gonna water today w/ some flowering nutes 1/4 str.

Kenpo is your temp gauge at your plant canopy,looks like heat stess.Also do you have fresh air coming in?Good Luck!

thanks for the help! my temp gauge is now at the canopy temp. still not going over 81f, its mostly around 79f with the light on and about 70 with it off....
When the light is off i keep the closet door shut when its on it stays open so i would assume it gets enough fresh air, but not sure??
