    UFO onc, several leaves have this on the tips

    Healthy roots and 2 new growths, and I have to repot it cause it's in a plastic pot an very top heavy. I'm going to give it a dose of epsom salts tomorrow. There's another onc next to it but it doesn't have any spots like this, which for me rules out sun burn. Both get 20-20-20 fert weakly weekly, rain hits that spot when it falls, and they get rainwater when there's no rain. Is this a mineral build up?

    Looks like it to me. Maybe this one is just more sensitive? Do you dry it out? I find that my oncidiums get leaf tip burn if I let them go too dry.

    That's a possibility, the plastic pot holds on to the moisture more here, so I wait a little longer to wet especially if the rain falls. Maybe I'm leaving it a little too long. Thing is, the two oncidiums I have are noticeably different. This large one has short erect, pale leaves where the other has longer greener leaves and the roots are plumper with a slight green tint, the larger one has thin white wiry roots.

    The leaf tip mineral/fert burn is a mystery to me. But I do know when the brown tips show "waves", it's fungal. In that case cut the tip off, treat with fungicide, decrease water staying on the leaves, increase air circulation.
