I've never had any hands on experience with scale rot, but that looks like it to me. But, please know that's a very amateur opinion based solely on a few pics.

Like tttaylorrr said, scale rot doesn't just come from humidity. It in fact comes more from the snake lying on wet or dirty substrate.

Also....phew on 7 weeks not months!!!

If you could share as many details as possible about your setup we'll be able to help you out better.

What type and size enclosure?
How are you heating?
Are your heat sources regulated by a thermoSTAT???
What are your temps?
How are you measuring temps and where?
Are there 2 proper hides?
Is the enclosure wise open? Or in a high traffic area?
Etc....
