I too brought a specimen of Den.Aberrans two months ago from a local shop. The fungus issues on the leaves were much worse than yours. My initial environment was too wet for it so I noticed the patches were getting worse. Then I adjusted the misting cadence + fan timing, I also cut away the bad leaves. Now I’m seeing relatively stabilized condition on my existing leaves.
I was thinking whether this is normal for all Aberrans. Since if you look at product photos from Brookside Orchids (where I got mine from), you can even see the spots on the webpage photos.
I see mine consistently sending new roots + a new spike. Maybe this is not so troublesome?
