Is there something wrong with my friend's Tolumnia?

[Wilder]

Hi orchidboard!

I'm plant sitting for a friend. He got a Tolumnia a week or so before I got two of mine. His Tolumnia is at least twice the size of mine but looks a little limp and wrinkly. My first guess would be that it needs more water perhaps?

He potted it in pine bark chips and waters it 4-5 times a week. It used to get morning sunlight (direct) for about 2 hours until 9am or so before it went back to a bright spot without direct sunlight. He fertilises it weakly weekly.

Thoughts?
