eh yea.. you should be alright. I wouldn't do it beyond the two week period though.. I personally... wouldn't do it if they were just a week into flowering.. but that's my personal opinion.if at all possible you SHOULD NOT transplant during flowering, could stress the plant into being a hermaphrodite (if it's female to begin with) but if you must transplant during flowering for some odd reason, during the first 2 weeks would be my best guess. Then give it a 50/50 mix of veg/flower nutes and then pray to whatever god you worship that it doesn't go hermy or male-out on you.
