Leaves curling up? Help please :)

[Snoopy36]

A few leaves on one of my plants are curling up/folding over, can anyone tell me why this is happening?

I grow indoors, this is week 4 into veg. Grow medium is coco.

Any help is appreciated! Thank you much

Have you recently topped or pruned? I see that for a week or so after topping branches.
