Wilting leaves on my Monster Phal

[susiep]

Do you all remember my "Monster Phal" that I repotted a couple months ago? It is still having wilting leaves. They are green, but soft as banana peels. Not all of them are wilted, but 1 or 2 on each plant are. Some are top leaves and some are on the bottom. There are 4 plants still attached to the one rhizome. It may be tired out from all the blooming. It ended up with about 40 flowers at one time last month. It still has spikes and buds to go but it is slowing down. I am thinking of taking it out of the basket and maybe mounting it on a large branch. I could wire the rhizome to a piece of wood very easily. Maybe the roots need more air. Here are a couple pics of the rhizome and the new basket. I don't have a pic of the wilted leaves. You can't tell by just looking any way. It is only when you touch them that it is apparent. It doesn't seem to be just a water problem. Any suggestions?
