Thank you all for your responses. I have my 2 orchids in a sphagnum mixture because I mistakenly ordered it from repotme.com. I prefer bark but the bark mix from Home Depot was buggy. I do think I had the moss packed too tightly so the repotting should help. I should have taken a photo of the lower roots when it was unpotted. They seemed to be wrapped in white fibers so I followed directions on some orchid sites to soak the roots for a few minutes in hydrogen peroxide. I'll check them again soon & take a photo if they still look funky.
