First time grower need help determining early sex!

I am a first time grower and so far the plant looks like a female but I am unsure I'm going on about 4-5 weeks of growing now. and I'm being wishful and hoping it's a female but if I can figure the sex out now it would be nice so I know whether or not to toss the plant. These are the best pictures I can come up with. These were taken this morning. Also does anyone have any tips for watering? I just use a spray bottle and spray the dirt every other day. Like I said I am first time grower, just experimenting and jumped into this without knowing anything, really.
