Thanks for your dedication in researching this problem, you truly are a
pal!!

So far its you, Susan and Rob that think it may be light related, and I'd
tend to concurr. Also you point out that I'd see it in my leaves, and I
recalled a recent purchase of plants from Carmela which are much lusher than
any of mine are, so I think that pretty much is heading me in that
direction.

You also hit the nail on the head by saying that I could err in not having
the freshest potting material in these plants, but they aren't the oldest
either... So I'll put that into the works along with Wendy's idea about
systemic pesticide. Both viable options to 'light'.

I'll lend one to a friend of mine and see if she can get it to bloom like
normal. She's a bettter grower than I am anyway. It would be a good excuse
to see what she can do with it.

Thanks for your help!

I love a mystery as well as the next person, and I've spent a couple of
hours trying to research this in my orchid books, and there are
absolutely no mentions of this symptom. From what I've read, though, if
you had too much light, you'd see that reflected in the leaf
color/health. And the fact that the plants are setting sheaths says
that they are inclined to flower. Perhaps it is another environmental
condition: not enough light, pollution, degradation of potting media,
etc.

If ALL of your orchids are experiencing this malady, it might be an
idea to do an experiement in light, room environment, loaning a plant
to a fellow orchid grower to see what happens, etc. It certainly sounds
like a frustrating situation. If you were in my area, I'd be happy to
swap plants with you to see what happens.
