Q.Unknown Plant
I live in Henderson NV and grow many vegetables and fruit vertically in large outdoor planters with much care and good commercial soils, nutrients and drainage. I planted two fresh, dried cantaloupe seeds in each planter and, as vines began climbing from two, the third sprouted and is growing this small, upright and unknown plant (photos attached). I have no idea what it might be but I sure would like some advice from someone who does. Thank you very much.
