Phal potted in a soil based mix, good or bad ?

[Asher]

Hi everyone i'm sure you have all heard this question a million times before but i'm torn on what to do

I purchased a new phal a couple of weeks ago from a supermarket, it is now in full bloom, growing a new bud at the end of the flower spike and growing a new leaf. These all seem like good and healthy signs to me .......BUT when i watered it yesterday i noticed on closer inspection that its potted in soil with large bark pieces on the top.

I've heard that phals shouldn't be potted in soil based media so now i'm quite worried. Should i repot straight away or wait until its stops blooming then repot. Or should i just leave it in the soil stuff as it seems to be doing ok as it is.

Any advice would be appreciated
