They are Stipules you are seeing not pre flowers on most , Your plants are too young and only starting to get pre flowers,
The fact that you think you can smell its male gives me serious doubts over your experience , As there is no difference in veg between male and females smell , The little pre flowers you have in pic 4 100% looks female , Another few days and you will see
I suggest you chill out and ask on here before making decisions over feed ect , You seem a little to hyped up or nervous to make big decisions
Just relax , I will give you a follow & any advice if i can ,
