How big is the pot it's in?
Is it rootbound?
Kinda looks ok to me, but if you do repot, go with your final pot size to minimize stress throughout your grow.
U don't need to re-pot just yet. I'd wait till it's a bit bigger and stronger and can take the stress, however minimal it may be. ... But that looks to me like there's some tin foilage up in there, if so, take the foil down it's not helping
Tin foil reflects more heat than anything else, and can burn. Flat white paint is suprisingly the best with like 80% reflectivity. Myself, i can't just paint my wood-paneled closet white, so i use mylar emergency blakets. They aren't the best by any means, but they're super cheap, $2 at wal-mart, and they work.
