Phal with yellow wrinkled leaves and spots on blooms

[vladkes]

Hi,
You know how some people are born with a green thumb, well I’m quite the opposite. So no matter how much I love orchids I never dared to buy one. Be that as it may, I got a beautiful Indigo Phal as a gift 2 months ago. I was also told that all it needs is 3 ice cubes once a week.

I first noticed a problem a week or two ago, the leaves started to look limp and wrinkled a bit, also dark spots appeared on blooms. And it just got worse, the leaves started to yellow, and the blooms are falling off.
I’ve read some posts and I am still at a complete loss of what is causing this. The plant was somewhat close to the window, could this be sunburn? Or are the black dots sign of fungus? I was using 4 ice cubes a week to keep the plant watered, could this be over/under watering or maybe the ice cubes was not the way to go? I looked at the roots on the inner pot, some are a bit yellowish but most are light green and there’s no odor.

Attached are some current pics. Any help would be greatly appreciated, I really hope it still can recover.
