Help! Do I have mites?

[Lefitte]

So I was handling my Cal King, Eir, tonight and I found a strange mark on her scales? Some kind of damage? She has always had perfect scales, sheds, health. Of course after noticing that I looked closer and found a darkish spot on her scale. I cant tell if its a mite under the scale or if Im being paranoid. I didnt noticed the scale being raised or messed up at all. I checked her face and cloaca and saw nothing out of the ordinary. Her stomach is harder to check but I did a little bit, she doesnt like being turned and its hard to shine light on her belly. I checked her water and nothing. She's been using her humid hide which has been dry for days (paper towels) and I found nothing there. Her humidity has been a little highbwith her new cage (60% when I prefer 40-50% for her). I just bought new bedding, hides, and branch. I did not clean the grapevine thoroughly (didnt think about it).

What's up with her scales and should I be worried about mites? I didnt notice that scaley opening last night when I handled her for a long time. Help?
