I think I've now got Curly Top disease (tomato mosaic virus).

I looked at the picture and based on that would not and could not make a diagnosis of Curly Top Virus, also known as Beet Curly Top Virus.

Your picture shows a plant with curled leaves, but many situations can cause that.

Curly Top virus is spread by beet leafhoppers. Do you know them to be in your area? Do you know this disease to be in your area? I ask b'c most Curly Top disease is restricted to the arid SW.

Why not check with your local Coop Ext agent first as to even the possiobility of Curly Top in your area before we move forward here.

Well, this is exactly what happened with my tomatoes (down here in south central Texas) - first a few, then almost all plants. I freaked out at first, then calmed down about it - I was just going to keep watering and feeding, and see what happened. Mine look exactly like your pictures. Tried foliar feeding and the curling went away. It came back again after a growth spurt, I fed again, curling went away again. No idea what it is, but I'm guessing it's a nutrient deficiency (I think one of the deficiencies does this). Can't hurt to try to fertilize. Mine are making tomatoes like crazy, and have been curling off and on for over a month, so don't do anything drastic.

Let me know if you find out what it is, and I will do likewise. I may try some Epsom salts.

Check out this link to photos (found in the HELP!!! Tomato Problem Solver 2 thread). Mine look like various variations of some of these, including copper, boron... My organic fertilizer has some of these trace elements, so maybe that's it. (I never use any pesticides or sprays, so I know it's not damage from those, at least in mine, and mine look just like yours).
