I have a grow tent, 600w LED veg/bloom light. Currently on Veg setting, about 14" away. They are falling over, I had lights higher at 18 and before that around 24", seems like no matter how far or close they are falling over. I cant seem to find the "sweet spot". I water them maybe every other day or when soil seems dry. I have a small fan circulating air, temps are good as is humidity. What can I do?
