I'm posting this question here first because this issue might be native to our area. If I don't get a response I'll post it in the Growing Tomatoes forum.

I've planted 18 plants all in containers. I did containers last year and they did okay. It was my first year so it was a learning experience. So, here's my question I have 5 plants that have started something unusual (IMO). The plants all look healthy, leaves are green, however the edge of the leaf closest to the stems are pale yellow! They don't appear wilted or crunchy, aside from the color it looks very healthy. I never grown the varieties that are affected so I don't know if it's typically of the variety. The plants are:

Snow White

Snowberry

Peche Jaune

German Johnson

Red Yellow Cap

Any ideas? Thanks for your help!
