Some of my plant leaves are curling up, but only bottom leaves. It looks like heat stress but I think its something else, because why then only bottom leaves curling up, top ones would be the curling up also. Take a look at the picture guys, maybe you know a reason why it is that way. and what to do.

I thought the same thing that lighting is incorect. But previous grow didn't had any of these problems with leaves. And I think if lightning would be incorrect, top leaves should show curling as well?
I'd definitely look for pests, mites cause almost this exact issue, but along with that growth gets very slow and the upper leaves don't grow very big. If plant is clean my next thought would be incorrect lighting.
What do you do for IPM? When I had gnats on a run back in 2019 this is what it looked like near the beginning.
I will be following the post to see what the popular opinion is.
Good luck 🤙🏻🌱🪴
