Well i would not go and cull this thing just yet curious how old is it ???
I does look like balls forming but i always wondered how many cull to quick give it another week or 2 seriously be 100 percent positive ,, Can't imagine how many culled a female plant thinking it was a male
for instance my plant last week was showing me signs of being a male plant and was both unhappy and also happy as its one nice naturally growing plant with perfect structure if its being either male or female ..
If it was to be a male it might be a good stud, nice tight internodes , nice bush lateral branching etc growth rates fast but not overly 5th - 6th week veg and today the plant decided to spread its legs only to show me its a women
