Phalanopsis not growing

[SteveM]

Hey All,

Again thank you for all responses and feedback. I have this Phal that I got from a local supermarket in Aug. It was a white phal NOID. The flower was very large and maybe 4 total. the leaves are tremendous, however it has not produced a new leaf since then, a good 4 or 5 months. All my other phals grow like 7 leaves a year, if not a keikie and none of those plants has been distressed and have not died. But I do know each plant background is different. This one keeps losing the bottom most leaf, like one every month or so. Lost 2 total besides this yellow one. I have posted a pic of the yellow leaf and the underside of the last leaf that remains (green). I was thinking that the no growth was attributed to some hormone or plant regulator because these leaves are unusually big compared to all my other phals. I suspected virus as well, being that maybe it just doesnt have the energy to grow more. Anyways with the underside green leaf pic I kind of suspect virus more. the dark patches are dark green where the main leaf is a little lighter. I have it quarantined to the best that I can, I do not plan on testing for it, but I have not seen any pics of viruses like these markings, but I do know there are a lot of viruses out there besides the most common 3 or so, and I am not the best at virus identification. It gets medium light, I can read a newspaper for like 6 hrs, no direct sunlight. and I do not water too much or too often, fertilize once a month right now, was every 2 weeks. I treat it no different than any other phal, I just recently took it out of pot to inspect roots and there were a few dead ones but had plenty of green ones. Dead ones were trimmed off. I feel this plant is on the way to orchid heaven. This plant showed from the leaves that it had a hard life, had some scabs from what I think was edema, I tried to give it a good home but am getting less hopeful with this one. Any ideas anyone. Thank you for the help.
