Peloric phalaenopsis with black leaves

[dgermak]

I found this little guy struggling in a grocery store. It had little blossoms that were too cute not to try! Question is what is going on here. Is it some sort of fungus that can be treated with Physan 20? I have it isolated from the others in my collection until I can figure it out. The white does not scrape off and the black is dry and leathery not squishy. I am hoping for something like sunburn or cold damage, but it’s just different than I’m used to seeing. It does have some decent healthy roots and I just gave it a soak as it was bone dry and blasting many buds.

I have a proper pot and medium so once I know how to proceed I will get it in the right situation, I am ok if the blooms need to go right now.
