Dude I have done something along the same thing! I was doing a outdoor grow but started to late and my plants where 10-15cm when they started to flower and I put them back into veg two days ago under 24/7 and one of my females started growing balls so its a hermie but can this plant now flower it self and I will have 99% females or 100% hermies? Also it is possible to put them back into veg they have been flowering no more than a week. I know I have stressed my babys now but they wont all turn into hermies? If they dont how long will they take to recover the shock???
