Question, I have a phal schilleriana "pink butterfly", I have had for a year now. It was potted in a peatmoss based potting mixture. It has now gotten a white cast on it and I would like to pot it in the regular phal potting mixture. Would that be fine or should it go back to the peatmoss baseed mixture. It is growing nicely and has healthly roots. Any help would be appreciated.
