Transplant?

My 2 week olds are huge and I was planning on just flowering them in 1 gallon pots but made the room to flower in 5 gallon pots... Is there an age or stage other than root bound that I can't transplant or is this okay.

I would repot but wait at least 2 weeks before switching to 12/12 they will have a chance to become more stable in the medium and less stress. They will have a huge explosion of growth too! Just don't repot while flower or to close to the switch.

sound advice from maine buds, also remember what soil your using as regards to feeding before switching don't want it too hot!!
