New to Orchids - bought vanda seedlings without realizing difficulties.

[King_of_orchid_growing:)]

The Vanda in the third photo has another leaf that was damaged. It's the central most one. It will recover. Don't worry about it too much. I've had this kind of stuff happen before. As long as there are a few leaves and lots of roots, it will bounce back. It will either grow a new leaf from the center or it will create an offshoot from the side.
