Normao or Not Normal

I know that most orchids don't like water on their leaves...and some really don't do well at all! I've got 3 paphs with, what I believe is water damage to the leaves. None of my other paphs exhibit this situation even though they get wet from time to time. I try very hard not to wet them but in the course of watering the GH things happen. They always dry within an hour or so. My question is: Is this fungal, bacterial or just dying leaves? I know old paph leaves(recently flowered) die, but this is only on 3 plants and looks more than just leaves past theie prime. In fact you can see that it is affecting some of the newer growth. The leaves where the discoloration is located is dry and just keeps working its way back to the crown.
