Is my baby poop normal?

First time mom here! My son is 9 months old and he just pooped this. It’s a grayish color and is a little worrying. He’s on Enfamil gentlease and didn’t really had a purée and only wanted the teething crackers, yogurt bites, and formula. He normally has that and his poop would be green, but it looks gray. Please help me out.
