This is my first time growing tomato seedlings. They are 3 weeks old
and growing large. All was going well until today I noticed some of
the older leaves on the Brandywine plants are begining to discolor. It
almost looks like the green is rubbing off in a large blotch in the
center of the leaf. The color is paler that the rest of the leaves. I
haven't been able to find any photos of diseases that look similar.

I/ve noticed the same thing with my seedlings grown under lights - a lighter
green patch in the leaf/s center. I/ve sen it happen with Bell peppers,
too.

Not to worry. When all is said and done, it won/t be a problem.

Harden off your plants for about a week when min temperatures average ~55°F,
set them in the garden, and you/ll be fine.
