Bud Blast :(

[Leafmite]

If the air blows directly on them, it might be. My daughter lost her blooms due to a cold draft. The phal is now re-blooming on the spike and is putting up a new spike...and on a table over the heating vent. The table keeps the air from directly hitting the flowers.
There are other reasons for blasting, too. These just seem like the most common reasons.

It doesn't blow directly on them, the vent is off to the side. There is a window nearby that may be drafty, but we have thermal curtains and I have not felt any cold drafts while over there. It does get cooler on the outer ends of the apartment at night (our thermostat is right in the middle so it doesn't measure the cooler ends with the big windows that well), but still the lowest I've seen my agrometer is 65 degrees. Though it has gotten as low as like 38% humidity. =\ I'm starting to think the humidity is the issue. I'm not too sure how to raise it, though. Maybe a table top humidifier?

Humidity could definitely be the problem. Our house is very dry this year because of the cold outdoor weather we've been having. I put my daughter's among the other plants for better humidity. For some of my orchids, I bought a clear, plastic drop cloth and covered the shelves to keep in the humidity...a makeshift greenhouse. I really haven't tried any other methods on raising humidity so I can't really advise you here.
Hopefully, you will get re-blooming and enjoy flowers after all. Good luck.
