weird leaf curl - photo

[Illegal Smile]

I've never seen this before. This came up literally in one hour. There are 4 plants in this tub, they are 3 weeks old. The two in the back suddenly got this leaf curl, while the 2 in front are fine. They were fed Sun and have been great looking since. The 4 in the tub immediately beside this one are also fine. Because the others are fine, I don't hardly see how it can be coming from the water, nor do I see where it can be coming from the air. These are in DWC under 250 MH

whatever you are feeding it isnt right, the leaves are trying to release whatever you gave them, hence the upturned tips.

That makes no sense since the 2 that are in the same water are fine, and they haven't been fed anything for 3 days.

what the RH and temp. air circulation? ventilation? I can see water accumulation on the resivore lid, you need to light proof that shit.

All factors are fine as evidenced by the other 6 plants that have no issue. These are about to be moved into individual coolers for flower. That light is hurting nothing at this point.

well since you know everything, pull the goofy plant and call it good.

Heat stress/fan burn would be my guess, but only a guess.
