Sorry man, looks like spider mites. Find 'em, kill 'em and make sure they don't reproduce. Then do your best to keep yourself sealed off. Also, the little fuckers spread really fast so keep it away from any other plants you have.
Yep, looks like mites to me, as well. Look under that leaf, and if your eyes aren't too bad, you should be able to see the tiny bastards. Sorry bro, that blows.
