baby eastern painted turtle

I got my turtle a week or two ago. he's shedding on his arms and legs. he's started shedding a few day ago, and I don't know if this is normal or not. I feed him hatchling pellets and carrots. he has a basking area with a normal lamp over him for heat, I take him outside to get sunlight once a week. he's in a 10 gallon tank, and he has a filter. I found little specks on his tummy, there not white. it just kind of looks like his skin is peeling. is this because he's growing or is there something wrong with him?
