Scale Rot??

So I need not panic when I see the humidity hit 67% + when not shedding? And then bump to between 70% and 80% when in shed?

Their temps range 88 to 91 hot side and 78 to 81 cold side.

It's high humidity combined with low ventilation (and improper temps doesn't help) that causes RI and a variety of problems. For example, if someone just lives somewhere where the humidity in their house is 80% and their enclosure has good ventilation, it is also totally fine.
