Leaves wilting after 48 hour photoperiod, lack of water or air?

Just like it says, my leaves are wilting after I sent one of my plants to start flowering, I put it under a big ass box for two whole days, came back and it has lots of new growth but looks pretty f*cked up. The soil was pretty dry for about 2 inches but then it got really moist again, I flooded it with water, and then I'll check on it later today when I get back. What else do you guys think it is?

The new growth is still doing really great, but a bunch of the old foilage is really ugly, curled leaves, and it just looks all droopy and wilted. I cut 2 fan leaves off that got light burn a week or 2 ago with a sterilized razor, they looked about 80% dead anyways. Hopefully it will make more growth else where...

Will need pics. Its hard to diagnose anything without them.

I don't know how to post pics, I want to start an album but I only know how to upload my pics to become my avatar. I'll probably end up asking in newbie central...
