I have a question about an orchid. It is labeled as Epi. Star Valley x
Joseph Lii Lake View (I'm not sure about the "LII" - everything is
capitalized).

Lately I noticed some leaf damage. The plant has otherwise done well.

I posted 2 pictures on the web:

Notice in picture 1 the area of dead tissue. There are 2 leaves on the plant
with this damage. Also on picture 1 is an area of decreased pigmentation
adjacent to the dead tissue area. Several leaves have just started to show
this discoloration with lighter green coloring. On picture 2 you can see the
area of dead tissue, and to the right of that is the area of discoloration.
Several leaves have this discoloration, though not has large as in picture
#1.

I have isolated the plant away from my others. When I was taking the
pictures today I noted some hard scale on a couple leafs, but I would not
think scale does this damage.

Fungal? Viral?

How do I treat?

I have sprayed it with Physan 20 (1 tablespoon per gallon); today I used
neem oil, too. Any other suggestions?

Thanks so much in advance...
