Cattleya Leaf Discoloration & Wrinkling

[astrumes]

I noticed an odd Discoloration on this mini cattleya's older leaves where the center of the leaf is pale and slightly yellowish.
The affected area is also rippled/wrinkled as if dehydrated, as is the bulb itself.
The leaf's outer edges are not affected, creating a ring effect.
The newer bulbs don't seem to be affected but I do see a little discoloration beginning on the bulb closest to the affected end.
Not sure what this is and wanted a second opinion before I go in and chop this plant in half. Please let me know if you've seen this type of thing before! Thank you!
