Give it a bit more time, sure its probably a male but wait for more balls to appear, i have had this and thought a male plant but was too lazy to cut it and two days later i saw white pistils. Please disagree with me people but this is just preflower and not yet flowering even if it is gona be a male, if your short of space just take it out of the grow room and leave it somewhere round the house, if it dose turn out male kill it but i still think you need more proof, those balls grow quick and in a couple of days it will be covered in one or the other. Just don't panic, plants are slow and don't run about worrying so neither should you, take some time to form a desicion here with this plant as will be good for future identification of sex of plant. Peace
