What's happening to my Phals!!!!!

[BikerDoc5968]

So several weeks ago I took all the chids outside onto the deck for the summer to clean the greenhouse of my algae problem. That worked out very well and all the chids were very happy in the shade of my oak tree or so I thought. I expected some problems because of the debris that falls out of trees, etc., but things were just fine. Then the past several days I noticed crown rot on one plant... then a spot on a leave and then another spot and another crown and.... I have been diligent about removing water from the crown and keeping them clean and since they were outside I have sprayed with Physan 20 more frequently as a preventative measure. Now I'm onto surgery, cinnamon and hydrogen peroxide and still am having a leaf problem. I assume this is bacterial and not fungal. Some thoughts/help, please.
