Leaf Rust?

I've got a strain dependent issue that's affecting

my outdoor crop. But only 3 plants are really effected by it. I got clones early this year, one is very very old and has it the worst. I am told it gets leaf rust?

It's effecting two of my other plants from seed (Different strain). Other strains are not effected in the same garden of 50.

This is from the least affected plant.

Dealt with it a couple years back, copper helped get them through but yields were definitely lower

I've also seen leaf hopper damage look like that.
