damn think i screwed up! help!

i had 2 plants 6 inches tall and put them into flower to see if they were male or female. well they were female so i put them under 72 hrs of light to git them back into veg! well like a dumbie i put them back in 12/12 2 weeks ago and they are doin nothing! havent grown a quarter inch and no new sets of leaves. do i need to chuck em or what!!!!! thanks

You really messed with them look forward to hermies unless you are lucky. Just leave them on a consistent light cycle from now on growth will be slow for a bit as they re-adjust.
