Hey Morgan! Nice new Phal.

You've gotten some good advice here already. I would definately repot all of them. Your new one looks like it's in yucky old Sphag moss. Bark is much easier for beginners to work with. The old Sphag is most likely very compact around the roots and if not monitored very closely will develop root rot. For now just don't water it as often as the others. When it's done blooming repot into bark.
The only thing I would add to encourage blooming is fertilize regularly. I do once a week with Greencare MSU. You can get it from Ray Barkalow here on OB. You also need to be sure you are giving them adequate light. The leaves look like they are a very dark green. This indicates to me they aren't getting enough light. They should be a light to medium shade of green. I have mine sitting in a bay window facing south with blinds and I am also supplementing with T5 flourescent lights. Ross has already covered the cooler winter temps.

Keep us posted.
