Oh Ace242, are the flowers on all of your plants or some? Some plants will show sex early. They are probably jusy pre-flowers if they have not been put into the flowering light cycle just yet. Don't worry about them. Just watch for any males flower that may pop up. I'm not sure if they will, but some male plants can start flowering early as well. Depends on the variety. But at least you can tell the sex early now. Here check ot the link.
