generaliztion for soil -- canopy matches root zone. think that's more for younger plants. i had 7-gal soil grow before that probably didn't fill entire pot with roots but was quite large.
That canopy is justifying a larger pot, i think?
if coco, you can grow huge plants in smaller pots. Somethign to consider if that's the case, but you still don't want it to get rootbound.
Likely has some holes in bottom. So, you can see if it's cramped and bursting at seams. Maybe you need a few extra days or not etc.. logistics may determine 'need' more than anything if it's not cramped.
