Did I nute burn my plant?

I think i may have nute burned the plant a little with superthrive.



Because some of the leaves are starting to cup.



It should recover, right?
I did a mini flush with pure water and I'm going to see if it comes back.

doesn't look too bad, if any.
is that tinfoil?

I agree doesn't look bad....if any doubt FLUSH FLUSH FLUSH\

Raise the light some she looks a little stressed...Leaf curl....

Thank you for the replies, i really cant raise the lights because of the way their mounted. and as for the tin foil it will be replaced by some Mylar E-blankets as soon as i can find some.
