Leaves curling up like crazy all of a sudden in late flowering

Hey guys!
Got two plants about 8 weeks into flowering and over the past week or so their leaves have started to curl up A LOT. I can’t be light being too close since that hasn’t been an issue and I moved the lamp up a lot since this started happening.
The only possible reason I can think of is that it gets pretty cold in the grow room during lights off hours due to the climate being at it’s coldest now around winter. Could cold cause curling leaves?
Thanks in advance.
Here are some pics

Cold doesn't so that heat does. What's your humidity with lights on?

if your in soil it could be salt build up. pull one up out of your pot and look on sides for the salt. Pretty sure that's the issue

Good luck

Broad or russet mite damage looks pretty damn spot on to that including the shiny top side of the leafs.

It sounds like 3 good leads so far. I thought it was too much light but you said that can't be it.

Lmfao God you are dumb. Some more false infospread by your stupid ass. Cold can cause leaf curl. You're just full of wrong info. Youd think being as old as you are. You wouldnt be as stupid.

You got a strong play or just the weak sauce you've been delivering for the time of your being here?

Need better pics. Turn off your lights and snap some new pictures.
What are your temps hi/lo and what's your r/h?

This is your clue

But I'm sure there are more established members on here that are gonna put you on the wrong direction just for the fuck of it

Btw, it looks like heat stress.
