The bottom line is that the early stages of pre-flowering is too early to tell for sure if you have a male or female. I have, however, compiled the BEST graphics available (at least that I’ve found) to help all my peeps out there make the best judgement on the sex of their plants. Thanks to Old_Phart for a couple of these (from his link). The others, I can’t remember where I found them, but props to the person who did them and supplied them.
