hey guys, this is my first growing experience, just would like to know if this plant is a male or a female... i already had to kill 4 of my plants cause they were males... really hope this one is a female so its been 2 week that i gradually started reducing the light (18-6 to 12-12). here are some pics of two preflowers, the first one is at the top node. i think its a female, but im not sure at all... any other guess ?
