Phal potting/crown rot question?

[Slobo]

I have phal that didn't flower for year and a half or more. It had a crown rot. So 3 weeks ago I puled the crown leaves out (they were all black and dried). Treated the crown with cinnamon. I didn't really expect this plant to survive.
Suddenly the new plant start to emerge from the side of the old one (is this keiki).
Well, the new growth stop growing. So this morning on my regular watering cycle, I puled the plant out of the pot and I found tons of dead roots ( mushy, hollow, no blackened roots). I cut all the bad ones and left it with 3-4 healthy ones. Treated all the cuts with cinnamon. I used my regular potting mix (bark, charcoal, perlite) soaked for a few hours. After repotting (into the smaller pot 3") I watered the plant with my standard mix, fert 125ppmN + seaweed. I didn't add K-L-N concentrate as I thought it would be the best to do that at next watering cycle. I left the plant in a shaded area and I'm planing not to do anything with it for a period of 2 weeks.

Is this how should I treat this issue? Do you find any mistake in this procedure? Please let me know.

Thanks,

Slobo
