Well, Im no expert but am in my first sucsefull harvest week (yay to me). but anyway i would recomend picking up some calmag plus from your local hydro store. besides that your plants are to small to see sex, you wont really see that till your like god damn theese things are taking forever. lol...
I hate those people that say my plant is one week old and its obviously a lot older than what they say that makes me mad.its like saying when your five im going to e as big as my dad(when plants little you say its going to be big) this is ok! but when your as big as your dad you dont say your five.
