Breast feeding and green juice.

My baby poop was green and she is strictly Breast feed she is 6 weeks 5 days old and I just started drinking a juice with lots of veggies in it. The juice it's self is green. That is her first poop that has been green. Usually it's a yellow colour. Would it be normal that if I drink green juice packed with vitamins it could be causing for her to have green poop too ? She doesn't seem any different or even fussyer than usual anyone else gone through this? In the juice is spinach, kale, celery, cucumber, carrots, Lemon, peppers, ginger, maybe a few other veggies.
