There was never anything in their droppings, no markings on them, nothing to indicate that they were having any problems at all other than the fact that I could see the mites on them.

I do have some good news though, somehow, the mites seem to of disappeared. Ive checked them the last 2 days in a row and I can't find any signs of mites on any of them. I really don't know how to explain it, maybe they weren't actually reptile mites, I guess its possible that they got infected with some other mites that were just living on them and not actually biting them and they just moved on. Ive spent a lot of time scanning their shells and faces looking for mites and as far as I can tell they are gone.
