Vanda - phyllosticta leaf spot?

[desertanimal]

Is that what this is? I've kept this in "vase culture" outside since I got it in early summer. It's been in pretty full sun for most of the day except in late afternoon and is only protected from wind in one direction. I soak it every day to twice a week, depending on how often I remember. It's grown lots of new roots this summer and the tips are still in active growth. It's grown one new leaf and started a second IIRC. I wouldn't be able to give much more light than it's had or more air movement. It grows with my Cattleyas, and they don't show this sporting. It's the time of year where I move them in at night due to temperature and I'll soon be moving them in for good for the winter. Should I worry about this spotting?
