I bought this plant about a month ago at a big-box store. It had flowers on one pseudobulbs and buds on the other. The buds on taller pseudobulb blasted but I didn't think much of it. Yesterday I noticed a strange dark indented pattern on the top of the leaves of the same pseudobulb that had the Bud blast. If anyone has ideas on what this is I would really appreciate it. Meanwhile I've quarantine the plant away from the rest of my collection.
