Help me save this mini Phal!

[The Mutant]

Please?

This is the one of the four minis I purchased about a week ago and just as I feared it's not doing so great. The first thing I did was to re-pot all four of them in sphagnum since the one they stood in were rock hard. During the re-potting I noticed that this little guy barely had any roots (I suspected something was up with it since its leaves were not as in such a great shape as the others being a bit floppy) and I've been worrying since. Today I did as you're not supposed to do and picked it out of the pot to check on the roots' condition and except them dying a bit more, nothing has really happened.

How am I supposed to care properly for this one? What can I do to encourage some root development (I don't have access to any root growth hormones) and how do I keep it alive? What should I really try to avoid - keeping it too moist or too dry? Should I move it out of the sphagnum and into a mixed medium instead? Or should I just put it back and leave the poor thing alone...

Please help me save this one! Not only are the flowers illegally cute, but it has very dark leaves that are mottled as well.
