Lower leaves of lettuce going brown on the edges

What Nutrient am I lacking to cause the lower leaves of the lettuce to turn brown on the edges? See attached photo.

Thank you so much! That article has given me so much to look at. In the winter we have found that we need to increase the EC to help the plants grow because of short daylight hours. If we cut back on the EC then we will need to increase the light. Again thanks for your help.
