Need help on care of Tulip orchid

[Jules]

Hello all,

I need some help with care requirements of a tulip orchid ( I just bought it- 1st one )

I was so exciting to see my yellow tulip orchid at a show I attended that I just bought it without researching the care.

I got it home and found that the old roots were rotted pretty completely BUT the new growth has just started putting out roots.

I have the orchid in some damp sphagnum moss with leca pellets mixed in.

Today the 2 yellow flowers that are just ready to open up started to go brown at the tip of the bud. I put on a cool mist humidifier thinking the air was too dry (live in zone 5) hoping not to lose the buds. maybe with roots in bad shape the flowers are blasting?

Please help i am clueless on the requirements or this orchid besides "high humidity".
