Hi all.

Started these tomatoes from seed from the Ohio Heirloom store. We planted indoors under LED lamps. Since these first sprouted, this breed has had the edges of the leaves as shown in the photos.

There is another breed we got that looks very healthy, nothing on the leaves like this.

Any ideas what this could be?

We plan to transplant outdoors tomorrow!

I have trouble with black varieties doing this in my garden. I'm not really sure why they do it here, but they always grow out of it. I notice it mostly after transplant.
