Oncidium health question

[Pimparella]

Hi everyone,

I am new here and I am really looking forward to learning a lot from all of you!

I am in a situation which looks really similar to what farley101 has had.
I have this Oncidessa sweet sugar (which looks like the one in the pics) that it has not been too good for the past few weeks. Although I watered it as I know oncidums enjoy a fairly humid soil, the pseudobulbs started shrinking. By now I have understood that what most probably has happened is that the medium was not very good (too compact, mostly perlite) and not ideal for my environment and so the roots started rotting.
However, although most of the pseudobulbs were full of wrinkles, there were 2 new pseudobulbs (visible in the pics below) which were also developing new roots.
I decided to go for repotting and I did it 10 days ago. I put mostly bark and some sphagnum. Most of the roots were gone but there were still some left.

Anyway, 10 days after repotting, I am now here with these pics, there does not seem to be much of a difference with 10 days ago and I am not too sure what to do. Should I just wait or do something like sfagnum therpay.

What do you think?

I am really looking forward to your advices!
