Q.Why Did One of My Tomato Plants Turn a Yellow Green?
After only about a week and a half, I had purchased three tomato plants and only one became washed out and a yellowish green before I put it in the garden. They all received the same amount of water and sun, but were different types of tomato plants. It was the tallest of the three! Is this normal?
