Odd coloration and spots on leaves

[NYCorchidman]

The first two pictures are of Mitonidium Rosy Sunset.
There are many lighter green circular shapes all along the edge of the leaves. Not all leaves have these, but many do. Some discoloration are not circular but some random shapes. You have to really look closely to identify these although they are easily recognized in the bright light.

The next one is of Brassidium. Most leaves are even green, but some leaves show these lighter green spots toward the tips of them.

The last one is of Miltoniopsis. I have two miltoniopsis plants that show these bleached spots on their leaves.

These are not insect damage, so that is not an issue.
could be just physiological thing, fungus of some sort or virus of some sort. whatever it is, it bothers me so much that I just want to burn all the oncidium types and never get any!!!

Please let me know if anyone of you grow oncidium types and see this similar phenomenon.

Thanks in advance!

If they were my plants I wouldn't worry about it. Orchids arn't perfect and are going to have imperfections. Now if it's a virus that is a different story but of course you can't know if it has a virus unless you actually test the plant. Just my .

It's just that I have other things growing in the apartment. Also, these kind of things really bother me.
I mean it's unsightly big time!!!

I did get rid of all my oncidiums for just that reason! Then I bought a onc. twinkle, a zygo (same look), and burr. Nelly Isler. I am not getting the spots this time (could be these aren't as prone to spotting). I keep them in bright shade, give them a variety of fertilizers (I have even been dissolving Ironite in my water every couple of waterings), and I try not to get water on the leaves. Some say it is a fungus and that using fungicides help. Some mineral deficiencies are known to cause these spots in other sorts of plants and oncidiums grow very fast....
Anyway, I know how you feel.

I feel you, I am actually thinking of throwing out all the oncidium types that have spots and streaks and other weirdness. lol
It could be just nothing (but doesn't make sense, gotta be something), certain nutrient deficiency, fungus, virus, water, sunburn, ....whatever the cause is, it's just hard to single out which one. That is the main problem.
The fact that it not only looks ugly, it could potentially be something that can spread to others, I am considering dumping out them all.

I do love them for wonderful flowers and ease of growing.

so I'm thinking of getting the ones in flower and enjoy the bloom and then out they go after the blooms fades!
They are just endless of varieties that are so beautiful anyways and I don't want any more stress!!!

So far, miltassia, some brassidiums, yellow dancing lady, large sharry baby, one wilsonara are the only ones with no spots. So they are definitely staying.

Sharry Baby develops black spots when exposed to high light and that's just in their genes. and I know what those spots are supposed to look like.

Luckily, my shary baby is a spot free clone.

I just can't stand spots of unknown identity.

I hope by 'toss out' you mean 're-home'. The plants are very unlikely to be contagious and I found it to be very easy to find homes for them. The recipients are still very happy with the orchids. I gave most of mine away at my OS, a few to friends. It was fun!

Lol my Oncs look much worse than this! But they keep growing and blooming and I love them. If u wish to rehome them I'll take them esp if the have their ID tags. Lmk!

These pictures show relatively "mild" ones. I've had oncidiums with dark spots, which I normally cut out.

Except for a few rare cases though, those spots do not spread. They just appear and stay there.
I just really get bothered by them and about to stop having oncidiums except for the ones with no or little spots on the leaves.

I will let you know.
