My tomatoes leaves have a dark tint and slightly curled. No lack of moisture. What may be the cause? They are not ripe yet. Probably 2 weeks away. Thanks, Larry

This would indicate that the soil has too much nitrogen, or that the soil pH is a little low. You can offset this by adding dolomitic lime, and anything with a high phosphorus and potassium ratio.
