New grower with a hermie and a female

hey im new to growing but i planted 2 seeds a few months ago in a cornfield and now they are a couple feet tall one is a hermie(more male) and hasnt been topped and the other is a female and has been topped once or twice should i yank the hermie? i will add picks l8r

:EDIT: i also havent been feeding it just letting it soak up rain water and some ties giving it tapp water when it hasn't rained

 

i would but the are really close to each other like lil over 1ft so i think im gonna kill the hermie today or tomorrow cause i just checked it and its already opening the pollen sacks (hope its not to late) cause i really want some dank buds for my first grow
