Well, this morning things are looking worse. More droop!
I decided to take it out of the pot and inspect again, in case I missed something. I'll isolate it from the others. I don't want to get goofy trying to save a $20 plant and risk losing my collection if it's diseased. Potted roots are all firm, cream colored, roots on top are dry. Can't find ANY black spots or mush at the crown or underneath. So I continue to be baffled.
The top leaf is the rubbery leaf - now the second one is drooping even more than normal. Kevin, you might be right about the lack of water. The original media (don't know what) was broken down & holding too much water. It looked like garden potting soil when I dumped it. Since I repotted in bark, perlite & a little charcoal, perhaps it's just not getting enough water, or didn't like the new mix.
The new leaf continues to split as it emerges. I might add that this particular phal. has
always had somewhat of a droop to the leaves.
Mike: I tried the coir in another plant. The stuff I had was very finely ground coir - very messy to work with once soaked. I wouldn't mind trying it again but need to find something easier to work with, if there is such a thing.
(I mean coir that isn't like a ground powder).
