I found a seed in plant that is 7 weeks into flower

I found one seed in a plant that is only a week out from harvesting. What does this mean? Why only one seed and does this mean I had a male in my garden at one time? Or....did it go through a stressful experience and would that cause it to produce one seed. I may find more after harvest, but I found it so odd to find one right up by the tip top of the cola, just out of the blue. Everything on the plant looks healthy, large, and I see trichomes turning from clear to milky. I'm not worried that I won't have a great harvest, just super curious as to why there would be a seed. Thanks for any input.

May have had a male in there early into flower , you might have an hermie in there too

i don't know anything about this but i have seen alot of people have that but damn i wish i could get 1 seed every harvest lol. maybe its fem cause there's no males. =P
