Was it the oil? Could they have fried? Otherwise I'd go with some sort of
rot. Hawaiians have been known to lose entire crops of Dendrobiums
overnight. Unless its Steve's creeping crud.

Well, we have a little problem here. Walked out on the patio on Friday
morning and saw severe damage to a number of Phals. Mind you, seeing them
every day is unavoidable, so I can assure you that these probs were not
evident the day before. Clearly, something had been in the works, but I
hadn't noticed.

The leaves are turning yellow starting at the outer edges. The under sides
of the leaves look moldy and pitted. Some of them have what look like
sunken areas on the top of the leaves, but those are not soft. There is no
sign of snails/slugs, and those things would be unlikely to find them
where they live. There is no big web infestation, so I don't think it's
spider mites. My guess is some kind of mites, however. Saturday we sprayed
everything (*everything*!) with soap and oil with some alcohol thrown in
for good measure - 6 tb/gallon.

Pictures going up in abpo in 1 minute. I'm really worried. Here I teach a
class for newbies, and look what I've got.
