Concerning baby poop?? HELP TMI

Maria

My 6 month old son strained to get this out, it was somewhat hard and had this weird black/tan/green color. Hasn’t eaten anything blue or purple, had some homemade baby food last night made with kale and broccoli. He also drinks Enfamil GentleEase formula. Is this normal? Should I wait it out? See my Ped? Help! First time momma🙏🏻 Thank you so much!
