What's your setup like?
From the small photos, I think the turtle just needs a good shed. For it to happen,
the turtle needs adequate UVB (from UVB bulb or sunshine), vitamin E (like from
blueberries, sweet potatoes), calcium (from cuttlebone), adequate feeding
(pellets and greens), and basking until both top and bottom shells are dried out.
Follow the feeding recommendation from the main site.
Good luck.
