I bought some non GMo seeds for San Francisco Fog Tomatoes, as I live in San Francisco. I started them in Jiffy Pots on March 19th, almost a month ago. They busted ground within three weeks and grew to first leaf height and now have stopped growing totally. I have been able to see the second set of leaves for almost two weeks but they do not seem to be getting any larger. I was told to wait until the second set of leaves expand and then to transplant with all of the stem buried, in that the roots will grow out of the buried stems. I am concerned that I have the wrong info and should transplant them now. Am I just being impatient?
