Where is Bright, In? It's really hot for lettuces- they like springtime temps, water, after a certain temp they get long and bolt and the flavor can turn a bit 'strong', where also are you planting them? A garden? A flower box?
Your area has a lot more drought than farther north, too, apparently they tried to bolt from the start- hence the length and legginess, and also from lack of moisture there, try again in Sept? I think? When onions and cold weather stuff are getting ready or, until Feb/March when winter is gone
