Be happy it didn't go into flower early -- and may not know if it is currently in flower as it takes 7-10 days to see that development after it starts. You only know in a belated way when its in flower.
The pot may limit size of your plant too. So, potting up would be wise sooner than later.
As long as you don't molest the rootball or break/rip a bunch of roots, you should not experience all this "shock" i hear about from transplants. In 6 years i've yet to see shock from potting up. For every plant i've grown, i've done 2 transplants for vast majority. Gotta be 300-400 tranplants at this point and zero shock.
I saw a plant shocked one time. it was a dumpster fire clone swap plant with bugs chewing up its roots. I removed the substrate from the root mass by dunking it in a bucket of water and running water over it repeatedly to remove all the 'dirt' they called a medium. That plant took a week before it started growing again in a new larva-free substrate. That was the one time i saw a plant 'shocked' and the reason was quite extreme... not from potting up. Still zero for three-hundred on that front, conservatively, lol.
zero for three-hundred is not the odds you play at vegas.
