Growing Lettuce

I left my cos lettuce to seed last season in our raised garden bed. The new plants are now growing beautifully, but they are all quite bitter. Even the baby plants. They are getting plenty of water, being winter time! Any ideas as to why this may be and what I can do about it?

Usually if it's too hot lettuce can get bitter but I think it may have more to do with the soil quality, and/or Ph. I would look into the Ph and then the soil nutrient content.
