Leaves rollin upward

So my leaves are rolling upward a d its not heat or to much light because i have 6 plants in the same spot and only this one (safetymeeting) is doing this???

What effects one plant won't necessarily effect another
Looks like heat or light stress to.me

Is it directly under a light

Like Bobthe420builder said different phenos different reactions to different conditions. Unless they are clones from the same mother then they should all be the same! We’re they from seed or clone?

Okay u guys are right. Different strokes... and yes they are all directly under a light a piece

Looks like heat or light stress to me. Possibly both.

They can do that sometimes when you give them a higher ppm feed than they're used to as well.

Also everyone is forgetting that leaf edge roll up often happens because RH is lower at that leaf surface than it is in the air.

is that plant getting direct Fan air ?

it could also be what the others have suggested as these too can play a role.

the trick is to find what’s causing it now based on all the possibilities of why it could have happened.
