Sue - I don't know what else those lesions on the baby leaves might be? What else could make those marks. I ran a tissue along the bottom of the leaves and no rust. So you are probably correct that it isn't rust. What else it could be, I don't know. It is on several of the leaves of that seedling and it's siblings in the same cup.

Is it only one ones in the same cup and are they the same cross? Do you remember if there was any sign of it on them before they were planted? If you could take off an affected leaf, set it on a piece of white paper to stop the camera focusing on the background, and take a close-up pic of both sides of the leaf it may help. I'm wondering if it is something physiological, maybe nutritional. Do you know who the parents are?
