Help pls. To repot or not ..?

Hi all.. Landrace bagseed sativa currently in 1 gallon pots..
Should I repot or let it finish with those.About 3 months old. 3 weeks in flowering. The one in the middle also 3 months old. I Cut the top from a damped off seedling and put it in soil, somehow it survived.

Thanks in advance!

Sativa? Bag seed? You're gonna need a bigger pot than that.
I'd repot to the largest/final pot
Lucky you come harvest time

I'd transplant if they were in veg, but if your flowering them just let them be. Don't transplant in the middle of flower.

Good point Vindicated, I should of checked the pics closer...
