i will say this about that plant.. it is almost being over fertilized.. those leaves are so damn green... Be carefull... i would not feed it on the next watering.. are any of your tips turning brown
if it should show some female preflowers i would save it and cut out the male balls. if you may want seeds and it is a hermie, just move it some where to grow seeds on it own without knocking up the rest of you grow.
if it is a pure male plant you got two options. the one is to kill it and ditch it or do what ever with it. the other would be to let it grow a bit longer and then cut of a good branch you keep for pollen and get rid of the rest.
