3 phals, 3 types of spots
Default 3 phals, 3 types of spots

Hello,

I have a few things going on with different phals (2 NOIDs and one phal equestris).

The first is on a phal in semihydro. It's on a few phals in SH, not just this one. Initially I thought maybe too much sun, but then very slowly the leaf would be consumed, dry up and fall off. Then I thought fungus, and tried Cleary's but that only seemed to accelerate the spread and kill the leaf off faster. It's very slow, and takes the upper leaves. Looking for thoughts on what it is and how to treat. I included an image of the underside of the leaf, because it sometimes shows up there first (which is why I was thinking fungus).

The second is also a NOID in SH, but the spots are different and don't seem to do anything. Too much sun? Something more insidious?

The third is the equestris which had been fine until 2 weeks ago and now has these yellow blotches. It has been under T5HO for months, but I did try to move it to more shaded location. With the change in seasons, outside light from the window may be upping the intensity. I think this one more than the other 2 is related to change, possibly in temperature or light? I have other phals right next to it that are fine.

They do kind of look like some of the photos Iíve seen of orchid fleck virus. I guess my inclination would be to isolate the affected plants and play with lighting, temperature, and media and see if it self corrects in case it is due to environmental issues.
