Lepanthes acting weird

[Leafmite]

Being mounted, it would be tough to give these too much moisture, I would think.

Here is a thread on Lepanthes:

Dying lepanthes in terrarium? slow decline.

New sphagnum moss was too absorbent. And the container wasn't opened every day(I have school and I get too tired some days) to let air in.

Actually, it looks happier today than yesterday(also, it is two plants now), the roots are green and it is starting to grow new leaves.
