Hey Orchid People!!
Like Shannara, I have been gone for a while taking care of some personal issues in the family. It appears as if the Enc's really had a time of it from those scales. I looks like what's left after the scales were removed, the bruising of the leaves. I would change the media first, and the after it recovers from that, I would just continue to feed it some foliage booster and then wait for the new growth to come out.
