Yep, just let them grow. If the leading tip broke off, then one of the side arms will become dominate. Train that and let it go. Its early enough that you may still have a shot at a harvest.
Search for "Hop farmer"...who is Glenn Fuller. He grows hops in CO and got hit hard by hail a year or two ago. He documented how he re-trained and managed to get a harvest. Chin up.
