It's been pretty wet all along the eastern coast! I see a lot of water spots on your phals, can you keep them from getting wet? If the medium has been staying wet, maybe it would be a good idea to check the roots to make sure they are not rotting. Phal leaves and roots should not stay wet, especially if the evenings get cool as they have been here in NY. As for bacterial problems, I really am not an expert on that. But, I'm sure others on the board are, so hopefully someone with more experience will have some input
