Should I transplant

I have had these plants in these three-4 gallon containers for a month, The roots are growing like crazy but it is now day 6 flowering, so will the roots slow down? should I transplant so they dont get root bound? and lastly is it ok to keep them in there because I am using COCO Hydro set up?

Generally, I make it a rule not to transplant once I go to 12/12. I have never used coco but thats my .02

Leave them alone they will be fine in a 3 gallon

NO!! they will be just fine in those pots.

well good, I dont want to anyway haha, it would be a hassle to transplant a 3 gal pot
