Spots on leaves

[RosieC]

I think I have some more with it And on the phal I've noticed it on it looks more like the Cercospora pictures

The phal was right next to the Epi and the other two plants I'm suspect of were also on the same shelf.

I don't really have space to quaranteen with everything inside for the winter, and I am also struggling to keep up with my healthy plants just now so don't have the time or energy to try and save them. None of the affected ones have flowered in years anyway, all but one has never rebloomed for me, so I think they may be on the way out

I really think you should try to find out what it is to guide treatment.

Tucker is right, it is a fungal infestation by the looks of the yellow rings around the spots. It might have started with cold water droplets reacting to the light where the fungi colonized and started to slowly fester. Antifungal spray could have helped in the early stages....

I've decided to give the phal a chance in an area where I can quarantine it

I have some cattleya having about the same kind of stains. I think light is probably too strong ...
