so, the proof is in the pudding tho, bc I was helping buds and he asked what the issue was last week if I remember right, and he went ahead and applied my suggestion, and if you look at the plants, it’s almost like some form of clown magic, the issue stopped. And the new growth is looking pretty damn good to me, the old damage will remain that ship has sailed. I gotta be losing it or I need eye transplants. So if you want to fix and issue with lighting, less is more, set it high, with out put low, so you can “dial it in” to what the plant wants. Meaning turning up output, or dropping it back down. You back off first so it heals. You don’t need meters and Wands for that. also look at the new growth again. They look great. Any deficiency that some folks think this is would still be happening? Why is the plant better now if his feed is off? I do t think folks know I’ve been helping him for about a week already. So man, like I said, it’s all relative to your area. Ppfd get new folks in trouble. And meters and wands just muddy the water more. Imo we should be eliminating variables not making more.
