Brown Crinkly Belly Scales

I'm really sorry if I'm doing this wrong, please correct me if I am. I'm not used to this site at all.
But...

I just checked on her today and she has these marks on her belly. When I rubbed them with my finger they were crinkly at the edges. I have her enclosure set up with a humidifier and little digital humidity readers and I checked around to make sure nothing was too damp or too dry. It did feel too dry; so I wet it down a little.

To me it seems like she's lacking humidity? Maybe my humidity readers are broken. From what I've researched: BP's need 60% humidity.

Did she recently shed? It looks like it may be stuck shed. It should come off if you give her a bath for about 20 minutes. I keep my ball python at 55% humidity and for when he's shedding I get it up to 70%. I might be wrong but that's what it looks like to me, hopefully someone with more insight can give a better answer. :)

To me it looks like there are pieces missing from the edge of a few scales. That's not a big deal, if so...as long as you aren't seeing bleeding or signs of infection
(redness, oozing, swelling); when our snakes crawl over abrasive things like branches, this just happens now & then. Especially when they grab prey & then back
up or roll around with it (causing their scales to catch on something). No way to prevent it, really. The "dark brown" color you're seeing is actually her skin under
the places where the scales are missing pieces.

Either way, good idea to check your humidity...many inexpensive gauges sold are not very accurate. But I don't think this is a humidity issue.
