yellow streaked and spotted phal leaves

Do you think this is bacterial? If so, what treatment do you suggest? If not bacterial, what do you feel the problem is...and how should I treat it? None of these areas are soft and mushy...all are firm. Neither are they raised or sunken. Also, I cannot tell yet if the small, new leaves are going to be affected.

To me, it looks like sunburn. Where do you normally place the plant? Maybe you need to give a little more shade or distance from the light.

Hi, depends where it is growing, perhaps not enough or too much sunlight, sunburn usually burn the leaves and often they develop a burned dry area on the leaf.
Personally the new grow is green so plants is growing ok.
i would perhaps give it more fertilizer as what is wrong is stressing the leaves.
A good dose of Epsom salts over the leaves would help green it it also.
The bark does look rather large and need to be keep wet so the plant can produce nice thick healthy leaves
Good luck.

Oh, I see my mistake. I have been assuming that all sunburn would be dark and dry spots (as a few of my plants have experienced, unfortunately).

All of my phals sit on a bench in almost the back of my greenhouse, but the sun can be strong even there sometimes. I have a few small pieces of extra shade cloth that I can place above only my phals either under or on top of the 60%.
Thanks for your help,
Vicki

Thank you, Ron. Since you say that sunlight is part of the problem, I'm guessing that my phals are getting too much rather than not enough. As I was telling Trev, I have a few small pieces of extra shade cloth that I will use to adjust the amount of sunlight that they are getting. I'll place some above only them in my greenhouse under or over the 60%. Watering time is coming up in a few days and I'll add a bit of extra fertilizer then, also. I have some Epsom salt, so I will pour some over the leaves tomorrow morn.
Thanks again for your help,
Vicki

Ron, I've been reading a bit more about Epsom salt. I've ran across several conflicting comments as to how much of it to add to a gallon of water. What ratio do you mix together? Also, how often do you treat your orchid leaves with the mixture?

I use about teaspoon per 4 liters of water (about 1 gallon) and repeat ever couple of weeks, it is not very compatible with other fertilizer so use it on its own, just pour or spray over the leaves.
