Also, this is a photo of the foliage from seedlings that are 4 months old. As you can see, there is one leaf in there that is almost covered in rust! I suspect the rust will cover the entire leaf (and plant) before long. They have only been outside a little over a week. No rust was seen on this cross until they went outside. They were started and grown inside in a south window. I would have to say that this cross is a rust magnet! Would this current photo be rated as a 3, 4, or 5?

Maybe too soon to judge the little guys.
Since they have just been moved, they are highly susceptible.
Treat them for rust and then see what they do.

If all leaves get covered like in the pic, I'd say "5".
But even a #1 plant will get rust if rubbing against a rusty one,
so getting an accurate reading on the other seedlings may be difficult if they are close together.

But if that rusty seedling comes back for another round of rust after treatment,
the cure might be to just throw it away.
