First, passing stool on the third day is most likely the prior meal (13 days earlier) not that it makes any difference.
You indicated she soaks after passing stool, probably not an issue, mine love to soak in the water and no they don't have mites.
You also indicated she likes her damp mulch pot, very good!
Lastly you said she spends all her time on the cool side of the enclosure.
Are both the damp pot and water bowl on the cool side? Does she have a hide/moist place on the warm side?
And lastly, 84 degrees while might be ok for the warmest spot sounds a little too warm. May be warmer than she wants or needs.
I keep my breeders at 80 degrees constant during the daytime.

BTW, yours is not the first post I've seen with BRP, was the "P" a typo or ????
