Okay lets see here, Illusion first because yours is sadder and easier to diagnose. Your plant looks like you have very little air flow around it, and it also looks rootbound and N overdosed... but air flow is KEY to that plant's survival. The leaves won't heal, but the problem should not get worse.

Weedhound, I just noticed you JUST transplanted... 2 days ago~
I think that day/night wilt thing may be nothing more than transplant shock, and teh original problem was that it hadn't enough root space. This is one situation in which I would actually use SuperThrive in flower. NOT at the recommended dose though; I'd go even weaker and do a drop per 2 gallons instead of a drop per gallon.
It will take more than a couple days to pull out of this. Think when people take clones, for the first couple days they are often sad and wilty- don't fuss with it too much; those roots no doubt got pretty jostled and the tiny hairs damaged removing the previous 3 gallon pail from them .
I'm going to post this in the log too just to keep all the info in the same thread.
