Yellow/dying fan on Paph Fumi's Delight

[tcrane]

I'm so sad about this!

Got my first Paph - Fumi's Delight x (micranthum x armenicum) at the raffle at the SF Orchid Society months ago, it was doing so well, but in the last few weeks the largest fan began to yellow and wither.

It's in bark + some moss to help it retain moisture, in my living room near a CF light, but not too bright. I mist it almost daily, water weekly, it's kept moist but not too wet. Repotted it a few months ago without a hitch, the roots were healthy at that time and it continued to grow. Any ideas? The other fans seem to be doing fine, both have grown a new leaf.

The only thing I can think of is a humidity problem? We've been using the house heater more, but the general level in the area where this plant is hovers still above 50% - 60%.





Should I cut the dying fan to save the others?
