is my plant rootbound? i have a bigger put to tranplant it if needed ( pic to )

i veged for around 15 days now its been in 12/12 flowering for 7 days and ive noticed no more leaves are growing and no signs of pistils. heres a pic of my plant do you think the pot its in is to small for it? i have a bigger pot and im really thinking about transplanting it quickly. what do you think i should do??

It probably wouldn't hurt to transplant right now but you can probably get away with waiting another a week or so if you really have to for some reason. In the next roughly 2 months that it's going to take for your plant to completely ripen it'll also become roughly twice as tall and it'll need twice as much root space = you need a new pot that's twice the size of the one it's in now and you should be set until you harvest.

ok thanks for reply. i just tranplanted yesterday so now its in a pretty massive pot. no problems tho it was a success. but 8 days ago was when i started 12/12 and i havent seen ANY changes in my plant? the stems got a big longer but the leaf growth has completeley stopped and i dont see any signs of calx or pistils inbetween the stems or anything. i really hope i didnt start 12/12 to soon because i only veged for 2 weeks when apparently u should veg for 4 weeks. so my plant is probably being forced to flower when its not mature enough... i hope it doesnt hermie
