Phal: Small root system, wrinkled leaves and non opening blooms

[Yelena Kosh]

Hello all,

I purchased my first orchid on May 18th, 2014.
Right away, I repotted it in bark medium. But one month later, the blooms haven't opened yet and the root systems continues to die. The only remaining roots left are the superficial ones.

I read a bunch of info on the internet and watched videos, but I can't seam to get it right.

The bark medium seams dry to me and the roots looked grey, so I stated spraying small quantities of water on the top of the surface daily. The roots started to look greener, but the small bottom leave turned yellow.

What should I do to save my phal?

Thank you!
