repotting in flower

How far into flower can plants be safely re-potted?

Im pretty sure they can be safely re potted anytime, as long as you dont disturb the roots/shock them.

after the stretch there is no benefit to upcanning as root growth has just about ceased...unless you have a horribly locked up medium to address

i agree Kite high, except for the fact that, if the plant is rootbound and in early flower I would re pot because the plant would greatly improve.

Last season I did an Indica about a month and half into flower and didn't see any bad results.
