Poop looked like pesto

Just want to see if this is cause for concern Recently started LO on solids he's 5 and a half months had all the readiness signs and a strong interest in food. He had avocado this morning and has done 3 poops (prior to this he would only go like once every 2 days but an awful lot when he did) the first one before he had eaten anything was his usual alot, yellow, korma paste type. He's done 2 small ones this afternoon both were green but with the avocado not entirely unexpected and they've been more like pesto, almost grittier than before. Is that normal? After 5 months with a slow digestive system I'm not used to anything else 😂
