hi i am new grower but have freinds that are very competent growers they told me once you have you first 2 sets of 7 leafs then switch from 18/6 to 12/12 once plant shows you sign of sex switch it back to 18/6 this has worked for me fine and my freinds. hey who wants to waste money though eletric on males
