bigger pot

orite amigos
the plant pot ive used for my plant, the long feeder roots are out of the bottom of the pot, the pot is a normal bucket sized one with a hole in the bottom, shes about 3 weeks into flowering and looking tidy apart from my earlier problems!, would anyone advise to transfer to a bigger pot or leave it well alone, i water and feed the plant by means of a plastic bowl that is bigger than the size of pot that the pot sits in, as in an earlier pre flowering photo attached.
cheers

transplanting during flower is never a good idea, but another idea that might help you out is placing the pot you have now ontop of another pot, the roots will grow down into the second pot for more root growth.
