spots in leaves

[Diamond]

hi, I have doubts and need advice. The two first are from my Blc Chia Linn. It has this yellowed spots on leaves. i put hydrogen peroxid and didn't fizz.
3º e 4º pics are from Oncidium ornithoryncum I think they are increasing slowly. I'm afraid it could be a viruse. any advice will be very helpful.

The spots on the oncidium look 'normal' to me. I have read that if they have spots like that it means they are getting enough light to bloom well. Others say their are ways to prevent the spots and still get blooms...Mine has spots like that too. I don't think your Onc has a virus. Maybe someone else has advice on the Blc, though.

Thanks annie, I heard many things about this spots in Oncidiuns. Only checking opinion of my friends here.

Does any suggestion on my leaves of Chia Linn?
This plant has being a bit hard. Bloomed ok some months back, but it is growing very slowly and some new growths became dark and died. Only one of them is okay now. it is a huge plant.

I don't think that is virus either. That looks like either cell collapse, or more likely, the leaf was exposed to too much sun and the leaf started to blister but did not burn on the China Linn. The only way to really ever tell if your orchid has a virus is to have it tested though.

Cheers,
