you are right... they say you can even successfully clone a plant in its first week or two of flowering... but,, my goal is minimal stress during flowering.. think of it this way.. the more you stress a plant in flowering the more the growth is stunted.. the more the growth is stunted (during flowering) the longer it will take for the buds to become mature.
you know when you buy seeds it tells you flowering time? well thats only accurate under ideal conditions with no stress... is it worth it then? i dont think so,, stress the plant minimally in veg,, get it done and over with then while it doesnt really matter... not to mention stressing a female in flowering will increase the chance of hermaphroditism.
