Sometimes "Leaf Curl" disease
Sometimes "Leaf Curl" disease will stunt the growth of your tomatoes. It will invade eggplant, cucumbers, almost any fruit-bearing vine. It is a monster. Before planting may I suggest you "study" the plant, the threats (insects and pests) and decide what type of control you will use? It beats being so very disappointed. This has happened to me a few times. Read: http://pep.wsu.edu/hortsense/scripts/query/displayProblem.asp?problemID=501&tableName=plant and also http://pep.wsu.edu/Home_Garden/H_G_Pesticide_Info/? about pesticides. Take a deep breath and prepare for next season. One good thing is that you planted them "well" since they grew so tall! Best wishes!
