Keep an eye on the watery brown spots on the leaves. You could try wiping that with peroxide or putting some cinnamon just on the spots on the leaf. I find switching from soaking wet moss to straight bark to be too much of a change from wet to dry for my phals. I add some moss to the mix. If it's really bad, you might just have to chalk it up to a learning experience and treat yourself to a new one

Also, any firm green or white root is a healthy root and the more the merrier. Limp or soggy brown roots and totally dessicated ones are the only ones to remove.
