Plants Healthy but leaves curling under and creasing. Pics attached

Hello,

This is strange... The majority of my plants are very healthy. The ones in question seem to be curling the tips of their leaves under and in some cases creasing inward or outward. My water temp and room temp was cold for a few days with a drastic outside air temperature drop. But i think my air/water problem is solved. I have pictures attached.

Thanks

It looks alot like over feeding.

Possibly N toxicity or a pH imbalance causing a lock out of other elements.

I would personally flush for a few days with a mild nute mix.

Any taco'd leaves will generally not recover back to what they were.

Curling up at the edges of the bladed leaves is usually a sign of a humidity or heat problem. Where the humidity at the leaf is low causing the leaf to curl inwards from the edges.

In order to test if it is a humidity problem you will need to test using your gauge at the leaf surface.

Hope this has helped somewhat.

It is helpful very much so... I'm doing a flush right now. My humidity gauge says 20% at the leaf surface on average. I wouldn't have guessed that I was overfeeding because the majority of the plants look fine. We'll see what results of the flush.

Thanks!

Jondamon hit it on the head for ya. You got great advice.

When you see leaf tips do that, it is refered to as the "nitrogen claw". It is a tell tale sign of too much Nitrogen...

I appreciate the quick reply. After a flush and a cut back on the nutes they responded nicely. New growth looks fine and nothing seems to be getting any worse
