Orchid sick? Yellow leaves with black...

[TwinKarma]

So I just picked up a moth orchid and when I brought her home I noticed a couple of the bottom leaves were really yellow and had this weird bumpy leathery texture. One of them fell off and the other one broke off when I was worrying over it trying to get a good look underneath. Unfortunately when I looked yesterday (I only got her Friday) two more leaves looked like they were doing the same thing. I'm worried my plant is sick. I looked up pictures of crown rot but it doesn't look like that and the roots look pretty healthy from what I could see. (At least the ones in the bark a few on top look scraggly)


Anyway down below are pictures
