Flowering question With pics

So I have had this one going since the middle of February and since I am going home from college for the summer i switched it into the flowering stage, This is the 4th day into it and I have seen some pretty good growth at the stem. Could someone let me know if I should toss it if its a male or keep the female. Thanks for any help.

Male. Sorry dude.

Thanks man, how can you tell if it's a female? first time growing

Look at the nutsucks on it. They're little green balls that get bigger and bigger and sweel with pollen, A female would have 1 of these but instead of gettting larger they would open up revealing 2 white hairs called pistils

If the balls are on little tiny stems....it's a male...no stems, female.

Thanks everyone.
