If they are still young and haven't fully rooted yet you can try and scrape of the top layer of soil to speed it up a bit.
Transplanting to less moist soil is an option as well.
If you think you need to move quick and feel for more drastic measures, cut out a piece of the pot (and tape it back on later).
Never let the soil dry out entirely though, won't reverse the effect overwatering.
On soil Tensio meter > PH meter. Ah, just found my sig.
