I have skimmed this post so if I am re-posting any part sorrry. I would like to first say Big high humid species are prone to molt issues IMO because of a few things. Feeding mice I do not believe to be one of them as science has show rodents to be extra sensitive to Tarantula venom. leading one to believe the venom was designed for them in a way. but that is another thread. I have found the one largest cause of molt problems is: POOR LIVING CONDITIONS
Now I am not saying your not taking care of your spiders in any way, but it is more you not providing them everything they need. A tank with 3in of peat and a hide and a water dish is not enough. Now I do not know how your setup is so I am not saying this is you. I have seen some very large T.blondi that never had molt problems. And they all had some of the same things going on
1. large tanks
2. deep burrows
3. a moisture gradent
4. allowed to feed naturally (by this I mean not power feeding )
another thing I found that is bad is too much moisture body parts tend to get stuck when humidity is too high makes things sticky. which is why I have always said a moisture gradent is a must these big spiders know what they need so they will seek it out and if conditions are horrible they take their chance's.
so I hope this helps in some way and I wish the best for you T
