Thanks broyea, looks like the heat may be causing that. pretty sure i read that fresno farmer was using a shade cloth. he has a journal going i believe. ask him in his thread. he will give u the info I'm almost positive.
I know man, I knowits july, its hot, relaxe
I water about once or twice a week, depending on how dry the soil is. Although I did water them a day before it rained. (I didn't know it was gonna rain though)how much you watering ? looks like over watering to me .
I'll see what I can find.If it were an indoor grow I'd suggest using a silica product like Botanicare's Silica Blast. It makes plants tougher/harder, able to withstand stresses like heat, drought, cold.
If it's applicable to outdoors, I'd recommend it.
