Your problem Kathy is back when you first posted the images, it has gone down hill further. Yes I understand that it was overwatered killing the roots. So now you have gone too far in the other direction by keeping what is left, too dry.
I gave you a method above on how to reverse the trend. It will take at least 4 weeks to produce a few new roots.
Fertilizer is NOT a cure for anything. By in large, orchids are not heavy feeders.
