Leaf Curl

[Twitch420]

We are on our first round of veg and getting this leaf curl. I know heat stress comes up but lights are at 500 watts 3 and half feet away they were at 2 feet but moved them up . Room is controlled and is at 73 F . See alot of pictures on line but not quite like this. Any suggestions would be awesome. Thanks

I think It's a light defense.
How long has it been since you moved up the lights?

3 days just learning now that the curled leaves will not fix themselves new leaves look good I think we got it.

That's my humidity temp 72 constant

 

[DemonTrich]

Gotcha. Thought those were your temps swings.

I think like mother nature plants like a temp swing from day to night just seem to be happier with a 5-10*F swing.. Glad you got it sorted...
