Looks like it could be spider mites.

Check the bottoms of your leaves, they are REALLY tiny. There might also be tiny eggs near the main vein of the leaf. Post a pic or two farther out, so we can see the whole plant too.

Looking again I'm almost positive. I think I can see 8-10 immature(possibly eggs) and 1-3 Adults.

Here is one of my leaves after I "killed" them. this is after about a weeks recovery time.
