I am growing several heirloom tomatoes and the Lemon Boy has terrible leaf curl. I increase watering- it's on the corner of the bed so I thought it might not be getting enough, but no change. Don't really see any pests. Any advice?

This type of leaf curl is caused from environmental stress. Causes for the stress can come from excessive moisture and too much nitrogen, high temperatures, insufficient water or root damage of some type. In the case of physiological leaf curl, symptoms occur first on the lower, older leaves. If you over-water your plants in the beginning the roots can be damage and not show it for a couple of weeks. When the soil dries the leaf damage shows up and the water damage happened weeks earlier.

I agree with Luke about the leaf curl, but the leaf in the second pic shows clear signs of disease. Best guess is a spot disease. Begin treatment now.

No, but it does usually clear upon its own. Smiling
