I know this is old as dirt, but does anyone have any more info on what this is ? I have the same thing happening. I moved two outside, and kept one inside. The one I put outside is flowering as fast as the one I left inside. If not faster. It's way beyond preflowers. It's almost half a whole cola now. It's been about a month. Plants are a little over 2'. I mean if it will go ahead and finish, I'm fine with it. I just don't want it to get 3/4 of the way done, then say "Hey, I feel like vegging now". Know what I mean. lol Today was the longest day. So I just don't know what to expect. Oh, just to clarify, They were on 12/12 when I took them out side, for sexing. I'm not comfortable going by preflowers only just yet. lol
