most the time you can gently pull out of pot and not desterb the roots and see if they look black mushy if not you can put right back in the pot and move to get good sun and stop watering until it drys out.
if the roots are black and mushy you need to intervene and take all dirt off and rinse it clean cut off all bad black mushy rotted roots.if this happens take a few pics of it and post we will walk you threw this surgery. I think it needs to be in more sun and less water and these hybrids don't flower all the time. they set flowers and bloom drop and it takes a while to flower again.
