Vanda leaves yellowing and wilting.

[Perverockstar]

Hello. I got this Vanda tricolor a little bit more than a week before. Some bottom leaves are wilting and turning yellow, top leaves look ok. Normal leaf cycle? Something else going on?

I have it on a south facing windowsill. Temps are around 20-23⁰C. It will get a lot warmer in Summer. It is potted in Bark, I soaked it once a couple of days ago.







I have experience growing other genera but this is my first Vanda, so I'm learning.

Thank you!
