transplanting 2 weeks into flower is it a bad idea?

My buddy has a few plants they look good but not in big containers.. I think if he had 5 even 3 gallon pots he be in a much better spot. Using about 1.5 to 2 gallon now when he pulled his males wasent to bad roots where to the bottom of the pot though all where good looking . So he is in week 2 of flowering 13 days and looks good but in a month he gets root bound will he b screwed? If all looks good why change well because thinking in the next month he will run into problems . Soil grow going by the book plenty of light great air flow and temps are perfect. Thanks for any advice I don't want to tell him to do something and be wrong.

if you want to repotn go for it, wont hurt, just be gentle

K thanks for the fast reply. I have heard so many time it stresses the plant and my boy has done everything not to stress out his babies. I just don't want to see him run into any problems in the next month or so I will tell him to b super gentle .. thanks again

repotting always causes a certain amount of stress but if its done gently this should be minimum. any stress should be offset by the plants having more room to stretch out more roots and therefore allowing for better growth. i try not to repot in flowering at all but i have done it and i would say it slowed growth for around 4 or 5 days.

no probs, done it loads of times, little bit of stress can sometimes make the plant try harder...........
