Quick help -Phal flowers died & buds dry and fallen

[phoenixx87]

I wondered if anyone can help me I have an orchid (phal) and it had a bit of trauma the store I got it from kept it outside where it was very cold and wet though it is potted in bark so thats good, when I got it it had 3 flowers and 5 buds. We had some builders in and one put his foot through the floor long story short theres dry rot in the house so I had to move it upstairs. Since then the flowers started to close and fell off within about 48hrs and 3 buds dried and also fell off they didn't turn yellow just dropped (this has happened in the last 48hrs hence the request for quick help). I have been watering weekly with rain water and have kept it out of direct sunlight, and have tried to keep a bit of humidity by spraying the air with the rain water though not letting it soak the plant just mist a little. The roots look strong and green in the pot there's no black on them, the ones outside of the pot are green with some silvery areas. The leaves aren't dry and are green with no holes or damage.


Editd to add I misread budblast as where they all bud not where they fall off. I gave it a little more water, its not getting moved anymore its in a window that only gets sunlight for a couple of hours late in the day, I put a little cup of water on the radiator about 4ft away to add some humidity and I put a wood stick in and it was very dry so I gave it some more water. Is boiled cooled water ok? I just bought some fertilizer too. I don't want my other 3 buds to fall off does anyone have any suggestions and if I might be able to save it
