Yellowing leaves Peristeria elata

[Suzanne17]

Hi, everyone- I have a newly acquired Dove orchid that arrived with leaves that were slightly yellowed at the tips- from my reading that is normal for this plant. But today I have two leaves that are almost completely yellow. This happened overnight. I repotted yesterday and they were yellowing down the leaf but were about 1/4 down the leaf. Is this the fungus common to this orchid or senescence? The plant is in spike. Should I remove the leaves?

Last night when I repotted (I did this because it was a new plant and every new plant gets repotted no matter what) I found an ancient bulb buried way down- it was yellow and rotting so I snapped it off. Thanks in advance for any advice. I did read quite a few culture sheets but they weren't super helpful with my questions about the leaves.




Eta I will reattach the photos when I get to work so they are better resolution. I can't stand how they appear when uploaded via the app.
