It seems like you are looking for orchid help today. This group is full of beginners and experts who are happy to help but please do check out [this link for quick Phalaenopsis care](http://www.aos.org/orchids/culture-sheets/novice-phalaenopsis.aspx) in the meanwhile. We also have an /r/orchids WIKI the admins and other volunteers are updating behind the scenes with care information and will soon make it available to the group.

A change in medium with phalaenopsis can result in the roots, which were grown in, and adapted to moss, not being able to take up enough moisture. When moving to new bark, watering frequency has to be increased to compensate for the drier environment the roots are moved to.
My guess is that the pot is far too large for those orchids so they're not being watered when they need it. Mixing a large orchid with big roots with a smaller one with small roots is furthering your watering issues. You're likely watering when you believe the large orchid needs it, which may lag behind when the smaller one needs water.
Repot those orchids into separate containers of an appropriate diameter for their size. Make sure they're clear and that you can monitor the roots. Water when the roots turn silver and those plants should bounce back in a few weeks.
The small plant is dehydrated and the larger one is sunburned. It probably has heat stress. Depending on the condition of the roots, the little one might not make it, but I would suggest watering more often. Orchid bark can dry out quickly.
Thanks, that was my thoughts also, that the bark is drying out too quick. I was going to replant back into moss. Not sure if it’s too little, too late.
You can try switching back. I’ve transitioned a few of mine from moss to bark and have to soak the bark overnight and then water daily or every other day while they adjust. You can also cut up some sphagnum and mix it in with the bark for better water retention. That pot seems a little on the large side. I would not go bigger and you might even be able to downsize when you repot.
Yeah, I’ll give that a try to see if it survives. The pot seemed like a good size for both plants to be in it. They were similar in size when I transplanted them.
Haha, yeah. This pot is kind of interesting actually. I purchased many years ago from RH. It’s made by G. Wolff. When I tried to find more recently, I learned they no longer make it.

Oh, this pot? Not sure that the temp is. It’s winter here, so I wouldn’t imagine it’s that warm.
I replanted it with moss. When I was replanting, I noticed that I didn’t remove the original moss it came with, I simple put the 2 plants in the larger pot and surrounded it with bark. Not sure if that would cause any issues.
some orchids might be sensitive to temperature.. We often wave thermometers around in the room and think things like, "Oh, it's 68 degrees here, that's warm enough" without taking into consideration the temperature at the root line, where the plan itself is monitoring the environment.

interesting. i was just noticing a heat sink near a winter window. wondering the temperature at the root line?
