A couple weeks ago I noticed these grey markings on my little dude's legs but didn't think much of it, just thought it was him shedding in a weird way. He just shed his back legs and the marks have changed, they look a bit like a scar maybe? As you can see from the pics it went from grey to reddish/pinkish. I touched them and he doesn't seem bothered at all. He still eats fine, moves fine, etc. At first I thought it was maybe a burn from his light, but his basking spot is 110f and the other light is a reptisun T8. It's worse on one leg as well, and doesn't show up anywhere else on his body. Any idea what this is? I recently replaced his basking light with a halogen floodlight, could that be doing something? Thanks for the advice. Here are some pics as well, first is the spots when they first showed up and second is from today.
