Yellow/black spots under rhyncho leaves causing dehydration?

[Kevinthe3]

Can anyone please identify what kind disease is this. I've tried google lense and it says leek rust or something. Been spraying dithane m45 to it 4 times in 3 weeks now and there is no ain of improvement, no signs of new root growth too. Leaves are becoming more dehydrated. Ive tried watering it twice a day and still the same. The spots are found only at the bottom part of the leaves. Would like to have your opinion on this guy's.

I don't see anything that looks worrisome, any damage looks dried up. But the plant looks severely dehydrated. A bare-root Vanda needs daily watering.

Agreed, it all looks like past damage that has healed. The marks will never dissapear, but I wouldn't worry about it or spray anything but water on it.

The plant may not have a sufficient root system to stay hydrated. I would just keep watering it daily (at least) and hope it gets some new roots out soon. High humidity will buy you more time

Thanks. Got worried it may infect my other plants. Would try to up the watering maybe twice a day.
