Scale Rot Questions

Hello there! I'm currently combating what I think is a minor case of scale rot (I've included a photo below if anyone wants to weigh in on that - I've never actually seen it before).
I'm doing betadine soaks, and I have her on paper towels with just her hides. What I'm wondering is whether the humidity will be okay in the normal range of 55-60%, or if I should keep it lower for now.

Here's the photo. I know it's kind of fuzzy; unfortunately I don't own a macro lens or this would be much easier. ;D Any input is much appreciated.

I would keep the humidity in the normal range. If that is scale rott, it's not very far along and a single betadine soak should stop it. After the next shed, you won't even know it was there. Reducing the humidity can cause other issues (URI) you don't want to deal with.
I'm not a Vet - just speaking from experience.

Thank you very much! That's kind of what I figured, but I wanted to double-check.
