I've noticed a bit of curling and I think I had the led turned up to powerful. I've just started it on its 3rd week of green planet dual fuel feed chart if that helps ♂️ dwc. It was 20ish inches above the plant and turned up to 100%. I just turned it down to 50%. Was my led turned up to high or is it something else? Any help appreciated
Both, LEDs are usually 10-25% for seedlings, 25-50% for veg and 50-100% for flower. Also looks a little unhappy, can't quite tell if it's excess or Def
