Problem with tomato plants

The leaves on my tomato plants are curling, turning yellow, and have dark brown spots on them. This started from the bottom going up. Can you tell me what is causing this? Thank you.

If the leaves are curling and there is little yellowing on the plant, the curling is likely environmental and not an issue. If the plant is yellowing as well, especially accompanied by spotting or wilting, it is likely disease. If they are diseased, there is little to do but pull up the plants and rotate new plantings to a new location. Unfortunately in this case, it sounds like early blight.
