Phal suddenly going yellow and dry

[narquelie]

Thanks everyone for your replies.

I've been using Orchid Myst, for the past month or so, since I was worried about it only having 3 flowers. I've used it in the past as well, for a couple of months every year and it seemed to be fine (although this is the first time I do it when it's in bloom).

The orchid has been in its new location for about 3 months. It's also got considerably sunnier outside in the past month so that probably didn't help..? I don't have any east/north facing windows though.

I've never repotted - which is terrible, I know - because it seemed perfectly healthy until now. It's still got 3 flowers atm, is it safe to repot now?
