Darn it. I hate to make this post. You all are doing such nice things with your Cathy Becks but mine is headed the wrong way.
It came in two weeks ago. Because I was not sure how to repot I left it as it was until now. Yesterday I began to repot in a choir mix and found that in the two weeks I've managed to rot most of the roots.

I must have overwatered though I didn't think so at the time. I've had it in a cool room, averaging lows of 48° and highs of 70° Maybe as cold as it was I should have drastically cut the water.
The first photo shows the roots. I don't think all of them are bad, and I decided not to cut any away. The second shows it potted up in the new mix. I put lots of peanuts around it to cut down on the extra space. The mix was soaked in worm tea.
The room now has a humidifier maintaining at 50% or better. But because the roots are weak I've bagged the pot and placed it near my Phals.
What else should I be doing? Should I unpot and cut away the worst? Anything else? I've jumped in over my head

but I'm not giving up.
