Can I get some insight please? My top fan leaves are curling down and almost wilted today. It's only affecting newer fan leaves towards the top, not older growth. They are 2 weeks tomorrow veg tomorrow. They still have moist soil. I sprayed azamax as a preventive yesterday and I lowered the lights about 6 inches lower than I normally have based on par reading. I know for a fact it's not russet mites. I had my plants examined under a 100x magnifying scope. It looks like it would be but that's been eliminated. I'm torn between lights being too low or the leaves not drying out in the 4 hours I doused them before the lights turned on. I have to admit I sprayed the shit out of them. Could that be out? Thanks in advance. You guys have always been great.

Looks like nitrogen toxicity.

They don’t look too bad, still the right colour. I wouldn’t spray the leaves at all during a grow but that’s just me. They get all the moisture they need from the roots.

I see some small light burn and some taco going on in the picture. In the lower right corner.
could be the light is too close
