I bought a pot of 12 inches tall white phal a week ago with 4 flowers already in full bloom and 3 buds growing. I moved into my new room two days ago, and already one of the youngest buds began to turn slightly red. Just this morning the two buds left were still green and healthy when I left the plant by a south facing window, and I came home tonight to find all three buds brownish, droopy, and wrinkly. The 4 blooms are still healthy though.
So I took the porous plastic cup out of the ceramic pot to let it air off a bit, wondering maybe the mixture is too wet. I did figure that my room is a bit dry, so I got a dish of water next to my plant, hoping it would bring up the moisture a bit (My room's quite small.) The mixture inside the pot is still damp since I bought it, so I haven't watered the plant yet. My room's about 25-28 celsius, and there are no fruits in my room. As a newb, I really don't know if the roots look healthy or not, neither can I tell what kind of mixture it's in...
How can I save my plant? Could there be more buds growing from the tip of the stem later? Or is that it for the season? I read somewhere that after all the flowers have bloomed and fell, I could snip the stem somewhere to urge the phal to grow a side branch from another node. Can I still do that with this plant after the current 4 healthy blooms are done?
I really wish my orchid could talk and tell me what's wrong

I had always though orchids are hard to keep, but I didn't expect it to get sick so soon...
