I talked to them today about my tomato. Nice lady, tried to help trouble shoot, mostly gave me advice I already knew. She says that they get sprayed with daconil while in the greenhouse and that it should protect the plants for 8 days at the retailer, but that's generally where they pick things up. No consensus as to what exactly is wrong with the plant.
I guess I'm also getting a certificate but I have to fill out an email with the details, and to be honest I don't remember what the damn thing cost. $4 or something.
