Shelf life of nutrient?

Hi, I'm trying out a small bubbler setup with lettuce and a friend gave me a small jug of nutrient left over from when she tried a similar project at least five years ago. Does this stuff go bad, or lose its potency or anything? It's Hydrofarm Hydroponic Nutrient, liquid, all purpose 7/7/7 if that makes a difference. And would it be a good nutrient for lettuce?
