I messed up good this time!

Well I got lazy....and from reading other peoples posts in discussions of not using the same water to water orchids and not having many problems when doing so, I decided what the heck....it would really save me a lot of time for my mounted plants I dunk into water....so into the bucket of water, with the same water...to water all of my mounted plants. I started this about a week or so ago. Then just last weekend....I noticed some weird looking stuff on one of my mounts. My husband said it looked like a tree fungus you would see out in the wild....I don't remember it being there before...but that doesn't mean anything with me...lol. Then, I started noticing some white-ish looking stuff on my some of my other stick mounted plants, mostly just on the wood....it looked like someone took white paint and splattered it, but the white isn't fuzzy looking. So I watered using Physan 20 using individual containers and not using the same water, but now I am starting to notice it on some of my other stick mounted plants. I guess that is what I get, hope I can get it under control. At first I thought it may be because some of the sphag moss pads that the mounted orchids are sitting on stay pretty moist all the time, and some have turned a yucky green-brown color, and some of the roots don't look that great...they look the same color on one of my 'chids. I would take pictures, but I really doubt it would show up. How do I keep my roots hydrated and from drying out and keep the moss from staying to moist at the same time? Sorry my original question has turned into another question that should be posted somewhere else. Any opinions are much welcome! Needless to say, I have now gone back to watering the mounted orchids individually!
