Sorry mate, I'm just a newbie, can't help you with that. Just asked the temp as something similar happened to my plants and it was heat stress. But I'm using a 400watt hps and the temp was quite higher so it's not that... just hope someone helps you out! It's really shitty when something is wrong but we don't know why :S
Oh alrite, Yeah i thought it was a heat problem BUt the lights dont let off much heat at all, The Mylar sheets i have in there contain the heat well, but i have a good exaust system that keeps the closet at room temp, And yaeh its rely warm here this time of year lol
low humidity... i read on here.. somewhere.... that laeves will curl to hold or release moisture...... so cupping means its trying too retain moisture.... i really dont know squat but i read that somewhere...... if it helps...
seems like upping my 4" fan to a 6" fan i can better regulate the heat in the room, When it gets a little warmer in their i can just turn the 6" up to high where as the little 4" was just a Single setting. thanks again for the help
This tacoing is common to a couple differnt problems. I've found it's usually one of two things: pH problems, or heat problems (may just be the lamp is too close)
