I'm starting to get foxtails on buds closest to lights. Although I don't really care I am curious what is causing them. I had the same thing happen last grow but buds grew into the lights. This grow, lights (4-42w CFL) are about 4 inches above top of buds and when I hold my hand under lights it is warm but comfortable. Temperature in grow box is between 84 and 79 degrees with humidity below 50%. I know the most likely cause of foxtailing is heat or too close to lights but didn't think CFL's would be an issue. Could it just be generics?
