I'm actually really glad you did catch that, Kush. There has been some heavy pH fluctuation. I'm trying to keep it steady and it has been steady within the past week or so. I'm hoping the problem STOPS. I doubt it is nutrient burn as the nute levels have been at 600ppm MAX since the beginning. I dont think 600ppm is high at all for clones. Again, I could be totally off. But even as the nute levels have gone down from topping off, it still continued to effect the plant. Seems to effect mainly the older leaves. I *really* hope it's just pH fluctuation.
