Need input, first time in flower! (narkush,new blue diesel,anesthesia

I have seen most people post in threads that for flower they use 5 gal pots to finish, well I just transplanted 4 females from 3 gallon pots just 1 week ago and I removed the tray bottoms of the pots today and it's sporadic but it's like every other hole has at least 1-2 roots *starting* to grow out of the holes, they are about the length of a half inch (if that) outside of the hole.

Already only after 1 week it seems like it's outgrowing the 5 gal pot, is this normal or will I end up having to transplant again?

I've been using hygrozyme too so I know this has helped stimulate the root growth but I've used it only once for watering since it has been in flower.

Dude that's a lot of "?" , do your self a favor and buy a book.. best $20 you'll spend!!!!!!!

I only have one question.
