I was soaking my Xerographica last night and I noticed this white splotch. I picked at it with my nail and it didn’t move. It doesn’t feel particularly fuzzy. I also didn’t notice them anywhere else besides what’s shown in the photo. Could this be mealy bugs? Or just a particularly dense grouping of the normal white trichomes on the leaves? Should I try wiping at them with alcohol or spraying the plant with Neem oil just in case? I was hesitant to do that to an airplant for some reason.
