Baby poop - should I be concerned??

My baby is 9 months old and lately his poop has been watery and chunky. I’ve been trying to do research if that’s normal or not?? It’s green but it’s always been like pudding consistency and now it’s small chunks and watery but same color. Sorry TMI! He’s formula fed and has started eating more solids over the last month. I’m a FTM and not sure if I should call his doctor and I’m in the middle of switching to a new pediatrician since we moved :(

Thank you!
