do i NEED nutrients???

so my plants went 4 weeks before need some food. they are just starting to eat up their two round feed leaves.

my potting soil was orginally mixed with some chicken poop, bone meal, feather meal and pot ash.

im feeding liquid fish protein every 2-3 weeks since i just purchased it

So my plants have been in 12.12 and STILL not showing signs of sex......unless its just me

heres some PICS if you guys can help...ALSO some diffrent color on some of my leaves if some of you can point that out for me please tell me whats up THANKS...so FEMALE or MALE????

??????????????????????????????????????????

looking healthy! soil is nice and dry!

give me some close ups of the very top nodes, where the shoots meet the main stalk and the main cola.

how long has it been in 12/12?

they have been in 12 12 for about a week now...from seedlings more than a month now...this is taking way long than i expected it to be
