mmm on the second photo i think i see the sign of the victory ( V ) pair of pistils ... can u post a pic of the whole plant ?
take a lower leaf of that plant and another of another plant that hasnt shown any signs , smash one leaf on one hand and the other into the other hand , if u detect a diference in smell then its a male , males tent to smell like finished product more than females where chlorophil like smell is more intense get out of growroom to make that test
