Weird Leaves in New Growth of Oncidium

[KristenJ]

Hi everyone,

Recently a new pseudobulb on my Oncidium has been opening its leaves. However, I have noticed it has some browning and kind of sunken looking areas on the leaves. I am not sure if this is bacterial/fungal. I am concerned because a few months ago, this Oncidium was sitting on a shelf with 3 Dendrobiums that developed a possible virus. I have been spraying with Physan every 2 weeks since.

I am wondering if anyone has seen this before and knows what it may be. Also, because of potting media concerns, I am repotting this Oncidium soon and was wondering if I should just try to remove this pseudobulb. There seems to be no problems with any other parts of the plant.

Thanks!
