Problems with phalaenopsis orchid - Yellow leaves and blooms dying

[stefpix]

I took the Phals out of the water [and a small Vanda too], the roots seemed to get worse rather than improving. i checked they have some "eyes" for new roots - and even if each phal was a dollar I decided to stop. I mounted them on coconut husks.sideways with the leaves hanging down.
I feel that is the natural way they grow and I followed King's hints.
The rootless Cattleya or Lc is doing well in water. new shoots and maybe new roots. So is a NOID Vanda looking [but smaller] and 2 Oncidium alliance I got for 2 dollars seem OK in water. Also I am trying a small Den I got as a spare from Royal Orchid Club. Had very dry roots but developing new ones.

My [novice] impression for the few weeks is that Cattleya is the one that seems best in water.
My concern is what is just above the water level - not immersed. I wonder if it may rot or get mushy... but I have seen posts of people being successful.
