Not The Typical Transplant Q

So the question is I have just the month mark in flowering with about aprox 5 weeks left. I have some plants that I was considering on throwing in some 5 gallon pots (from there one gallon pots)

would it still be worth on transplanting or just a big waste of dirt to do so?

I dont think their rootbound but would like some bigger plants for obviously more budage

Thanks in advance

I don't know for sure, but it seems to me that what you don't want at this stage is increased root growth, which is what transplanting at this stage might produce.

If I were gonna mess with it, I'd only go up to 2-3 gallon . . . you don't want a bunch of root action stopping your bud action. Do you have room to top-dress the planter you're already in? If so, I regularly do this.
In case you don't know, top dressing involves removing top soil from planter and replacing w/fresh soil. Kind of a "breath-of-fresh-air" type thing for plants.
