Pot Size for Outdoor Auto

So I'm gona be growing 6 femenised autoflowering plants outdoors in southern California. I heard square pots are best for root development so I ordered some online. I also heard more depth than width is important. My pots came and I'm thinking that maybe they are too big to pot in because I've heard people say you don't wana plant germinated seeds into pots that are too big. So I got thinking and I'm wondering how can any pot ever be too big? I understand if it's too small but how can a pot be too big, I read something about if the pots too big the plant will use extra energy developing roots which will stunt growth above soil, but how the fuck could a seed know the size of pot it's in unless it's too small?? Anyway the photo attached is the pot size what do you think is this too big or should it work good??

Those pots are about 1 and 1/2 gallons. I use the same ones for autos all the time because they don't take up much space in the flower room. BigSteve.

You should probably start them off with a 5gallon pots id reccomend smart pots (fabric pots) but those you have are also good but not for too long. As far as transplanting during veg df reccomend 5-10 gal pots. Im not that experienced my self but I believe that would be a good option for outdoor.
