My bulbophyllum lobbi is not healthy

[Rudy]

My bulbophyllum is getting small spots on its leaves which over time start getting bigger all the time.
It started on one leave (the one with the big spots on the second picture) and now it's spreading to the other leaves (see the first picture with fresh spots).






Are these fungi, insects, virusses?
Can I do sth about it?
Or shld I ruthlessly throw it out?

hmm, my guess is fungi...
dont throw it out yet, maybe separate it from others.

hope others can give some advice...

Spray with a fungicide just to be sure, but I think it might also be sun burn. It looks like what happens when water droplets/ oil droplets are exposed to sunlight and burn on the orchids leaves (like a magnification glass). In any case, if it seems to be spreading, get a fungicide and spray both the top and bottom of the leaves and soak through the medium. Then move the plant to a location away from the others in your collection. It will not hurt to spray all of the plants with a fungicide. Also be sure to keep a fan blowing on your orchids that helps to dry them off quickly after watering. This will help reduce the chance for fungi too. Good luck.

Bruce is right, its not a bad idea to consider spraying it down. Air flow is important...both to prevent sun burn and to prevent fungus. Keep an eye on the spots for growth, and especially for watery or brown margins. A dead give away with a lot of fungus is that the edges kind of look like an expanding water spot that slowly darkens.

I had put it aside already as a precaution and sprayed the leaves with a fungicide.
Did not know about soaking the medium.
Will do so.
Thanks for the tips.
