Brassavola nodosa with dense black spotting

[isthelaststop]

Hello,

About a week ago, I moved a newish Brassavola nodosa from a pot on my grow shelf to a bark mount. I noticed when mounting it that there were a few black spots on one leaf tip, but didn't think much of it since the leaf tip may have been sticking a bit close to a light.

However, it's been getting a LOT more speckling (including a tiny bit on the 2nd leaf), and I'm getting suspicious that it's an infection and not from light. What should I do?

Have a look at the Diseases and Pests section of the St. Augustine Orchid Society Web page. It might be cercosporid fungi.
