Dendrobium Abberans hybrid with leaf spots
 

Hello everyone! I recently purchased this adorable new Dendrobium Abberans x (abberans x woodsii) from a local grower. I've had it for about two weeks now and began noticing some brown spots on a couple of the leaves. It sits about 9-10" under my T8 fixture in a northeastern windowsill and gets 1-2 hours of bright sun in the morning as well. It is also in a room that has a humidifier running most of the day, so the air stays pretty humid.

I am reluctant to think that these spots are sunburn, as the grower I purchased it from had the plant in a fair amount of light: so much so, that the new growth is a lovely deep red. Any advice or thoughts would be helpful, and I hope you all enjoy the little display of blooms that it is putting out!

My Dendrobium nobile types get these spots when their leaves get wet and I’ve had them develop on one of my Vanda and Epidendrum when they got wet at cold temperatures. I think it’s fungal but if I move an affected plant inside where it’s warmer and keep the leaves dry, there is no recurrence. I just let some of my outdoor plants live with it: I try to keep water off the leaves but it will show up after a string of foggy nights and seems mostly cosmetic.

Old leaves. Damage done and over,

Don’t worry about them at all.

Thank you both so much! I wanted to double check that there was nothing to worry about :) Happy growing!
