Actually plants can preflower showing secs before flowing but generally that's with non autos, and when you do extra vegging. An the last Post was right about time frame on an auto, u won't know sex until 7-10 days into flowering were u change light cycle from 18/6 or 24/7 to a cycle of 12/12

I've had plants show sex in less then 21 days but it doesn't happen often...usually around the 40-50 day mark i start seeing the pre flowers.
