Yellow & spotted phalaenopsis leaves

[Nameless]

Thanks for all the replies!

I really do not think that mites are the problem - I have never seen them (I think I would notice them) and no other plant has the same problem.

The keikis - it is phal pulchra which makes keikis really very often, so it does not have to be a sign of a problem (but could be, of course).

And what the fungal/bacterial infection concerns - is it possible that the keiki had the infection from the mother plant and when I potted it it showed no signs of infection for a year, and now (after a year) it shows the signs for the first time? What about some virus? Could it be? Hope not...

Hmm...well I don't know if the mother plant carries a dividing membrane to protect the keiki, but I do think that given the opportunity of stress that any disease would take the opportunity to show itself. I mean, it may not have mites but it may have had something before you got it that opened up the plant to infection. The reason I am thinking stress is because it hasn't produced new leaves. It doesn't have a spike coming from the center of the plant does it (top)? I didn't think so but thought I would ask. Have you used any sort of remedy on it?

ETA..Camille might know the answer to dividing membranes....

I agree that it is definitely weird that it did not produce a new leaf for over a year (especially when it produced a new spike and 3 keikis on two old spikes). No spike in the center. And I did not use any remedy, it seemed not to be spreading (until I have found the same spots on the repotted keiki).
