Not sure mites?

[Appalachian]

i have a Phalaenopsis brother pico and the bottom edges of the leaves are black kind of spotted. The plant had it when i got it, and i thought it may just be the coloring of the leaves. However they have become very soft and pliable, and are now starting to shrivel. Any ideas i could really use the help.

Do you have a photo of it?

The first one was when I got it, The second is the progression of the infection. The third is a dendrobium, I hope someone can diagnose. Thanks for any help you can offer.

There are larger versions in my gallery

I'm not an expert but the first thing I would do is look at the roots to see what shape they are in as well as the potting mixture (to see if there are signs of rot)
What's it planted in? how do you water it ?.

Sorry, I don't see typical signs of mites. I do see some wilt in the last photo, but that could be anything. Mites typically leave white wispy webs on undersides of leaves and if humidity is tyipical for Phals (above 50%) then mites usually aren't the culprit. I agree with nanella and check the roots. Unpot the suspect and check the roots. I know I have been surprised many times with what I found!

Potted in orchid bark, charcoal, perlite mix, with stones at base. Roots are in descent shape, a few signs of rot, i trimmed them and a couple dead ones, sprayed with organicide (sesame oil and fish oil) and dusted with cinnamon. I Water with distilled water(me and a couple of friends distill it while we are at the still) from a spring that i get drinking water from (surface manifestation of an underground spring very clean water) with a 3/4 recommended dilution of better-gro orchid fertilizer. I mist twice daily once at about 6:30 am, and once about noon keep lots of circulation

Not sure water has anything to do with it. If you are convinced roots are healthy, then I wouldn't worry. I still see no evidence of mites (maybe I'm blind, who knows )
