not enough to determine female or male.
you will find pistil grow earliest at the top of the plant. so dont go looking around the bottom. the thing that you are showing me is called stipules. study this diagram. print it and stick it on the wall to remember this. as u can see male and female have something like a ball sack but the female part is a bit longer.
but if your plant do become a female please buy a nice set of timer worth 20 bucks or more. do not settle for sumthing less than 10 bucks. trust me (sometimes they dont even turn off).
and listen to this part very very carefully.
do not do not do not do not do not do not.
i say it once again..
DO NOT interrupt the plant during flowering!!!!!!!!!!
once it's off it stay off for 12 hours. do not turn on any light that goes near that room. if you have to cover the growth room or closet with a solid blanket. it's extremely important unless u wanna start pickin the balls off (no homo) causing a hermies
