First question:
Recently the newer leaves are starting to look like someone sprinkled salt
on them. I tried to see if these dots might wipe off but they don't. The
undersides of the leaves look fine. Maybe it might have something to do
with the ants I see crawling up and down it. Also, I have read that all
passiflora incense are infected with the mosaic virus. Could this have
anything to do with it.

Which leads me to my next question:
If all passiflora incense are infected with the mosaic virus, can it be
transmitted to other plants?

I live in NYC (zone7). The plant gets full sun.

Thanks in advance.
