Female Or Male???? First time Grower

Hi, i planted 2 purple haze 2 weeks ago and since i planted them ive been with a 12/12 light cycle, and now they are starting to show these little ball at the top of the plant, i want to know if it is possible for the sex to show up this soon, since the plants are really small. i want to know if these plants are males so i can discard them as soon as possible.
Thanks

i think male but im no expert

chop,chop,snip and chop..and rip...

Male Alert Male Alert!

Kill it now...

well heres my 2..personally i have never seen a male form its balls in the center cola at the very top...everytime i have had a male the balls form at the leaf nodes...so i have no idea what that thing is....also my comp sucks so the pic didn't show up very well...but what would it hurt to let that plant do another week mabee 2....theres still time to grow more...lol

if you grow them out for a while youll see they grow EVERYWHERE!

So, Final word?
Chop IT!!!!! OR KEEP IT AND SEE

Chop It Down!!!
