How do you get the taste of fish out of the lettuce? I have lush looking lettuce now. Its about ready to pick and make a salad out of only after 40 days of growth. But I took one of the plants out and ate it and it had a very distinct fishy taste. I understand that it tastes like fish because there is a lot of water in lettuce, but is there a way to clean the water up so its odorless, yet still healthy and tastes great?
