Dying phal - help!

It's hard to tell with all the cinnamon you put, it might be crown rot.
The leaf that fell off, where was it growing? Was is a bottom leaf, or the newest leaf? If it was the newest leaf, and mushy at the base, it probably crown rot. It happens sometimes if you let water sit in the crown too long, like overnight.

If it's crown rot, one thing that may help is pouring a bit of hydrogen peroxide in the crown, let it sit, then pour out. I've also read that you can pack the crown with cinnamon after, but not sure.

Sphag and bag won't do anything until you solve the rot issues. Btw, since you saw mold on the roots, did you put cinnamon on them too? If you did, you really should rinse it off the roots right away. Cinnamon is a strong dessicant, and will literaly pull water out of the roots.
