I had my 2 week transplanted clones under Mars hydro 300w led set at 50%, then 4 days ago I turned it up to 75% set at 30" above canopy, temp fluctuates between 72- 78 degrees from lights on to lights off at 18/6. Humidity is between 46%-50%. Started getting canoed leaves on new growth...is this light/ environment problems? They seemed to do it a day after turning it up to 75%
