Not sure if it’s a male or female plant!

1 month ago when i came back home after vacation i noticed a small plant growing on terrace. I never planted it or anything but i always throw my weed seeds in this flower pot And my family has been watering it unknowingly. Since i have seen it growing well i have watering it daily. Any tips or tricks how can i make the most out of this plant and maximise its potential. I never grew any plant before so no idea how this all works. A guide on proper nutrients, lighting and watering cause till now it has been growing on its own with the help of sunlight, natural wind and just water.
