As Doc said and you now realize, repotting a blooming plant can be a mistake. Some would recommend removing the spike so the plant can focus its energies on getting reestablished. Before resorting to that, the plant definitely needs more moisture.
An alternative to soaking the medium in a tub:
- Put the plant in the sink (forget about that "germ" stuff - the plant is probably cleaner than you)
- Run tepid water through the pot to thoroughly wet it. I prefer to use the spray head for that, as it covers the medium more easily.
- Wait 30 minutes
- Do the thorough watering again.
That waiting period allows the bark chips to swell a bit from the first watering, which opens up the porosity, allowing the pores to absorb more the second time.
After that, each watering should be very thorough, but likely won't need the repetition.
