Virus on brassavola nodosa??
Hello everybody,
I have 2 brassavolas, one seems to be unaffected by this (it is a smaller plant), the bigger one, which since a week ago is living on my balcony (towards SE, full sun between 8-11) has several leaves with these spots on them..
I have taken them out little by little, now for the whole summer that will be their home..
I don't know what these are..First I thought they are sunburns, but they show up on smaller, hidden leaves too.
I really really hope this is not a virus 
Thanks for any thought.

Is that brown area in the last pic soft and mushy? It doesn't look like virus but rather some sort bacterial or fungal infection.

No, it is not soft and mushy, it is hard when you touch it, and it is a little bit elevated..
Thanks

Looks like burn to me even very bright hot sun can affect small tender growths .
I hate to say this but are you sure that is a B. nodosa ? the leaves don't look like one to me .. my nodosa leaves are more rounded stiff and pointed .. Gin

Yes, it is a brassavola nodosa for sure, i was asked before about this too..it bloomed until 3 years ago..
Some of these spots are on the opposite side of the leaf where the sun is hitting..so, i am confused, i thought they are sunburns too, but..
Thanks everybody

The plant I would get re-looked at because the leaves as you show are totally wrong for nodosa, no question, the spotting is due to the excessive light its had, its a feature that happens with brassavolas.

Yes it is a brassavola nodosa, here the flowers from 3years ago..
So, that is excesive sunlight? Then I don't know what to do anymore, I guess I will put her on shade..
I was told that didn't bloom because it didn't get enough light, it didn't have the reddish spots..
I took her outside, gradually, my balcony is sunny in the morning, as i have learned they like full sun..
Now it has the red spots, meaning that the light is fine, but also sunburns..
Thanks

Light doesn't mean burn. You can have bright light without direct sun, its a matter of observation.
