My tomato leaves are starting to curl. It stared at the top and now is moving down the plant. I have plenty of flowers and even 2 pieces of fruit. I tested the soil before planting and it was fine. I feed them, water by hand every other day. I just dont know what is going on. Does anyone have any ideas? I have posted pics so that you can get an idea as to what I am talking about. Thank you in advance for your help.
