[pleurothallid-l] Dryadella edwallii and some others

I recently purchased a few new pleurothallids for my orchidarium.  Most
of them are doing great, but there are a few that are starting to look
sad.  Dryadella edwallii is in about the middle of my orchidarium (gets
approximately 1000 -1500 foot candles of light) and doesn't really get
much of a breeze.  It is in a small plastic pot with sphagnum moss and
some perlite to help keep the medium airy.  Some of the leaves have
turned brown and some have fallen off.  I'd say the plant is about 1/4
of its original size.  I'm not really sure what to do with the poor
monster.

The orchidarium is kept in the middle of the house.  The temperature
generally fluxes from 70 to 75 F.  I water each of them (if they are
dry, which is usually every day) once a day and they all get a quick
mist.  The humidity fluctuates between 90 and 65% (occasionally it drops
to 53%).

Two other trouble makers are Scaphosepalum grande and Dracula chimaera.
These are my first "soft-leafed" pleurothallids.  The Scaphosepalum is
closer to the light (approximately 1500-2000 footcandles).  It was doing
great for about 2 weeks, and then I started to get some yellow patches
on the leaves.  I'm not sure if this is from the light or the misting.
I suggest the misting because the yellowing seems to concentrate on
areas where the leaves touch other things (a tall water dish and one
side of the orchidarium).  The other one, Dracula chimaera, is located
farther from the light (approximately 1000 footcandles) and is closer to
the fan (the leaves flutter in the breeze).  It has nice looking leaves,
but some of the leaves have started drooping.  I'm not sure it's because
of the fan because the leaves that are moving are not the ones that have
drooped.  Maybe it's the humidity or it needs more frequent waterings (I
have noticed that those plants closest to the fan will dry out the
quickest).

Any help would be appreciated.
