Help! Something has spread to most of collection

[gcc0008]

About two months ago I moved all my orchids, except two phalaenopsis, outside because I was not sure if they were getting enough light. I noticed spots several weeks ago on a cattleya and like an idiot did not take immediate action. Now there are spots on many of the leaves on most all my orchids. I need to know what it is, and how to get rid of it. My collection is less than 10 orchids and most have spots so I want to avoid disposing of plants to save the rest because there would not be much left to save. And as a note many of these were acquired bagged from lowes this summer, but the cattleya was acquired last February.

The first four photos are of the really bad cattleya
The fifth photo is of another cattleya
The sixth and seventh are of a bassavola nodosa hybrid
The 8th and ninth are of an epilaeliocattleya
The last photo is of new growth, oddly enough, on the really bad cattleya, so im hopind it still can be saved.

Thank you in advance!
