The Phal abuse ends here.

[cythaenopsis]

Here's an example of a Phal that has suffered from too densely packed moss potting and too much water.





I've since potted it with fresh moss, more loosely packed, and I'm going to be much more careful with watering. Thankfully it has two aerial roots that are at a low enough angle in the new situation to help with feeding, while new roots (hopefully) make their way down. The leaf showing some yellowing has already fallen off and the new leaf is aggressively pushing it's way to maturity.
