Serial Paph killer

[TylerK]

I seem to be completely clueless when it comes to growing Paphs. Though it's never been widespread, they all eventually seem to succumb one by one to the same disease.

It starts out as an orange tinge to the leaves...under the surface of the leaves, not on top. Pitting of the leaves eventually occurs. If left alone it spreads across the plant and it dies. Its not particularly fast at first; not mushy or smelly, so my assumption was some kind of fungal infection. I tried treating with phyton 27 on a few different plants, but it just seems to make things worse. The leaves start to yellow and brown desiccated spots appear.

This does not seem to affect any of my other orchids, and I grow a number of different genre.

Does anyone have any idea what this is or how to properly treat it? I'm sorry, but I don't have a picture a the moment. I can try taking one later today of a plant that I've already treated with phyton 27, but I'm not sure how useful that would be. The effect of the phyton doesn't seem to closely resemble the disease itself.
