Not sure what this is

beefsteak · May 1, 2015

The leaves on one of my super sweet 100's are getting small blotches on them and I'm wondering if anyone can tell me what this is. This is on a seedling under lights in the basement and it does not seem to be spreading to the other plants. I would also appreciate advice as to how to treat it and should it be discarded or separated from the other plants. The plants are getting large and probably tomorrow going out to harden off. Thanks, Rick

The order of the pictures is
first pic: top of a leaf
second pic: top of plant wilting somewhat
third pic: underside of leaf
fourth pic: underside of another leaf

looks like edema. If you google "edema tomato leaves" you will find photo's and information. Be careful to not over-water., that is the cause.

I did not know the name of it, but yes I agree it is caused by overwatering...

Thanks for the info, it's sitting out on the porch now with the rest of my tomato plants hardening off.
