I noticed a small lighter colored spot on my red-foots plastron today. My question is has anybody had any scale problems with their red-foots due to the substrate being constantly moist?

I keep mine on coconut husk in a closed terrarium with a pegboard back for ventilation. to keep the humidity up I mist 2x a day, which keeps the substate moist as well. Here is a pic, if anyone has an idea or has seen this please let me know. The mark is the lighter area just inside the torts right front limb.

That is a common fungal infection. It is often caused by tortoises sitting in the same damp bedding that has accumulated a lot of urine over time. It is also contageous and may be from another tortoise sharing the same sleeping quaters that may have the fungus already.
Sometimes wild caught redfoots and yellowfoots that are from really wet areas, or that have been held in dirty compounds before shipping will have it as well.
The good news is that it is relatively easy to get rid of.
Clean the spots by a light scrubbing with soap and allow to dry completely. Then appy one of the anti-fungal creams sold for athlete's foot or jock itch. It should clear up pretty soon as long as the bedding or sleeping area is also cleaned or moved.
If left unchecked, it can spread to the carapace and become very hard to eliminate.
