Scale Rot or Scars?

My cousin just got this baby Stuart’s Milk snake on December 7th, she was fed on Tuesday and I picked her up today and saw some weird looking scales, I’m not sure what scale rot looks like so I’m hoping someone can tell me what it might be and if it’s life threatening. The humidity isn’t too high, bedding stays dry other than when it’s lightly misted once or twice a day. I’m really hoping they’re just weird scales but I’m just not sure. Please help!
