Tomato trouble

I've got these 3 better boy tomatoes all next to each other out a row of 15 plants that in the last two weeks appear to have a disease. Could this be blight of something else? Here are pictures of 2 of them.

Are all the leaves curling or just the lower, older leaves? Is the new growth affected? If it is affecting the whole plant, it is probably not a fungal disease.
Several things can cause tomato leaves to curl. It could be a physiological response caused by weather conditions; too hot, to dry, too wet, too windy. Growth of the plant is usually not affected and the symptoms usually disappear when conditions improve.
This looks very much like herbicide damage. If you or a neighbor have been spraying an herbicide like Roundup or a product containing 2,4-D, this could cause the damage you are seeing if the herbicide drifted onto your plants. Herbicides can drift quite far if caught by the wind and tomatoes are very sensitive to herbicide damage. If this is the case and the plants survive, they will eventually outgrow the damage. Herbicide damage can also occur if you mulch tomatoes with grass clippings from a lawn that has been treated with a weed and feed product or a broad leaf weed killer. There have also been some problems lately with some mulches or compost made with hay or manure from fields that have been sprayed with the herbicide Grazon causing herbicide damage to plants.
Several viruses can cause curling of leaves, stunted growth and pale leaves. There is no cure for viral diseases and the plants cannot be saved.
Keep an eye on the plants to see if they improve/if the new growth seems normal. If they continue to decline, you may want to remove them.

The weather here has not been too severe, I live near Norfolk. The curling of the leaves was basically all over. No herbicide has been sprayed near them either. It's just the regular garden dirt, tomato tone, and pine straw. What's weird is I have a row with 15 plants and had these 3 plants side by side effected and these are near the middle of the row. I have pulled them up and planted some in their place. If anything else happens I'll let you know.
