I soaked a patch pre plant, and now the tomato plants now looked burned with curled leaves and small fruit... Melons and squash seem fine.
Might not be the gly tho.
There are other maladies that can cause the same leaf curl/stunted fruit thing with tomato plants.
Hot dry weather will do it, and there are several different plant viruses that do the same thing.
Mosaic and Yellow leaf virus come to mind, but there are others. Spotted wilt, curly top...
I've seen them all here over the years.
Uneven watering causes the leaves to curl and be leathery.
