Chicken Soup for kittens?

I switched my cats from Innova to Chicken Soup for the Cat Lover's Soul several months back (mostly for cost reasons). Now we've added two new kittens to the household. Is the Chicken Soup adult formula sufficient for growing kittens, or do I need to get a kitten formula for the little guys?

ETA: I don't know if this changes the answer, but they also get a variety of canned food. I feed each of them about 3oz of canned each evening, rotating between Chicken Soup, Innova, and Wellness.

NO the adult is not a good food for kittens BUT the kitten is a all stage which means it is FINE for adults
