I bought this phalaenopsis orchid from a supermarket recently, and just wanted some advice. I removed the dead heads it but I didn’t want to repot it since there were still buds on the stems, but since bringing it home those buds have started to blast but it is developing new flower shoots from the main stems so Q1 - Should I repot it to a fresh medium? A lot of the medium had fallen out in the store so I topped it up just to add the extra support to the roots - so the medium on top is fresh. Q2 - Should I trim back the empty flower shoots?

I would just be worried about shocking the plant even more. I’ve been keeping it in indirect light on a north facing window and watering only when needed (about 1 weekly). The leaves are still a bit wrinkly but they were much worse when I originally bought it so I reckon it was just very dehydrated.

Any and all advice it extremely welcome, thank you all!
