Phragmipediums assessment and repotting

Last year I bought a few phragmipediums, mostly besseae hybrids, because they are just so pretty. They all were strong multigrowth plants from Ecuagenera. They lived in the larger tank and instead of growing they were continuously rotting their leaves off.
They did grow nice roots, but with regards to their foliage - it was just diminishing.
There could be many reasons for it - too humid air in the tank, not enough fertilizer, keeping them in saucers with water. So I decided change everything.
I started my yearly repotting ritual with phrags - fresh media will help.
Here is my mix - large sponge rock with small fir bark:



Then I add some river stones into mix:



Unpotted Eumelia Arias, nice roots:



Freshly potted in their new home:



I decided to move them on to bathroom windowsill. There is plenty of light, not as dry as the rest of the house, but also not as humid as tank.
