Can someone please tell me what stage this is of growth.
That is a male plant. Flowers are puffing their pollen all over, are you looking to harvest the male pollen or were you hoping it is a female??
A male and the pollen sacks are open, hope you don’t have any females around Growmie 
Or anyone else in the Neighborhood!
Welcome to the community .
Male plant unfortunately as the others stated.
Also welcome to the forum 
That’s a lifetime of seeds right there. Seeing how I can make out other plants in the background. If you didn’t want seeds you would have had to catch him early on. The damage is already done. Live and learn.
Welcome, sadly a very painful lesson to learn.
