That is definitely a male part not sure if the plant is male or hermaphrodite
So what happens if I just snip that off ? That’s the only one. Probably from stress from topping
I don’t know is it a female plant? If so then you can just cut it off and watch it closely some will keep putting out male parts others will just have one or two
It has flower sites and its an auto WW feom ILGM.
Sorry that is some balls. 
@Skateallday55 When balls show, its generally something that went wrong with how your grow. What caused it? No clue. A simple light leak can. It sucks when this happen. Unless you want a male then its fine.
If it also has flowers, you have a Hermie. Still not good.
Oh shit! Headed to the tent to check mine out
Looks like you topped yours too. I bet it’s stress feom topping. As soon as I topped 2 days later I had pistils and one ball.
I’ve topped all but 1 auto. This was the only one to do that.
They all got flower sites, does it have pistils or white hairs?
Yeah its the stress feom topping . Gotta be
Mine has no balls
A few months ago I had a White Widow Auto that grew one male part. I cut it off and the plant grew just fine = great weed. I didn’t top it, though.
Any nute or lighting problems or changes ?
Yah it sure is
No, I hadn’t had any problems or changes; it was just after she formed “buttons”, i.e. she had just gone into flower, and it appeared in a very similar as yours, on a lower node, same area.
