No but actually thats kinda what I'm in need of because of my total lack of knowledge.. I feel like it should be very soon though.. I am needing to figure it out because I'm sure I have too many for my light at this time but once I determine sex I will be able to hopefully get rid of a couple/few.. Any advice on pre-flowers or determining sex or what have you I'm all ears, also if you have links and feel like posting them I'm all about reading up for sure.. I tried the search function but really did not find alot of great results, I will keep searching though..
