Just came in from checking the girls. The two plants I was getting ready to discuss have curling leaves at the tops. The rest of the plants seem to be doing fine. These two are the closest to the light (18 to 24 inches to the light) which suggested the possibility of heat damage in the making. While reading my bible I came across the applying of too much fertilizer spray too often. I have been spraying Neem Oil (leaf polish) in the early hours of the morning before the light comes on to handle an infestation of spider mites. I have so far seem to have cured the problem. However, is it possible that I'm spraying too often (every morning)? Could use some feedback!
