My male Buster that was a CL rescue also has a couple of scales that are off colored. Not exactly sure what causes it but he is very shy and healthy.

That is totally normal. We've talked about it on here a few times and no one really knows why it happens. It has nothing to do with humidity or anything. It's just the very top layer of scale that came off. The glossy layer. It's more common in pastels but happens to all of em. It will fix itself in a shed or two.

That can happen from bites, scratches, anything like that. Nothing to worry about, they will heal.
