advice for molts georg

I bought a tiny versi at an expo last month, they're about the size of a quarter right now and when I removed them from the container they were sold in I counted three whole molts in there. Since they've molted three times since they were put in that container, I wasn't expecting another molt given that the little guy hasn't eaten since arrival despite my offerings.

Turns out that's because they were apparently in premolt. Again.

Looked over just now and they're molting right against the vertical cork they live on, which is already stressing me out, but now I'm worried it's also too dry for them right now. In an attempt to avoid sudden avic death syndrome, I've just been keeping their water 'bowl' topped up and occasionally overfilling it just a smidge, but I would have raised the ambient humidity levels a little bit if I knew to expect a molt.

Do you guys think it would be better to top off her bowl/let some of the water trickle into the substrate, or would that be too potentially upsetting when she's in a delicate place? I don't want to startle them (sidebar, currently too small to sex but I'm defaulting to 'she' as wishful thinking).

EDIT: Never mind this versi is he fastest molter in the west and was NOT impressed by my 'I haven't had a tarantula in a decade' anxiety. She's doing the Fresh Molt Dance at a very awkward angle now.
