Potinara leaf never seems to open!

[denvervet]

Ok you guys and gals know your stuff, what's up with this?

I rescued an orchid from Lowes in the late Spring. Its a Potinara Kozo's Scarlet 'Vi-Emi' SM/JOGA. It had a new leaf so damaged it had to be severed. Then it got another new leaf about 3 months ago......WHY WON'T IT OPEN?

It gets a morning sun but only for about 30 minutes, then moderate to bright light all day, NE window, I spray it every morning and water 2 X a week since its dry as a bone in Denver with little to no humidity. Its on a humidity tray which I religiously keep full.

See pic, the new leaf is the one on the left of the pic.

I am going to try to put a 2nd pic on here showing some new growth I just noticed and the lovely roots.
