One seed on a female plant...

Hello guys I was just wondering how did I get this seed and if this seed will be a female. I will give you a little feedback, growing is fox farm soil and have been cloning the same plant for a long time. Never had a seed before and never had hermi's. This plant might have got stressed a the beginning, It just never took off as fast as the others and is now one of the biggest I have. With one lonly seed at the bottom in the middle. It has been budding now for about 6-7 weeks needs a little more time im in no rush.

And what would the chances for this seed being female...

good if its a hermie. if it was pollinated by a neighbors plant. 50/50

I found some seeds in the buds that I harvested. Not just one but lots and lots. This is my first time in this forum. How can I avoid seeds in the buds on my next harvest? Not sure if it's OK to post this question here. Please help and thank you very much.

avoid stress. light leaks and shit like theat. also it may just have hermie genetics in it. if u have run it a few times before without any issues i wouldnt worry now. also there is a spray called dutchmasters reverse it needs to be used with the other spray in the line. but its supposed to help keep female plants female without it turning hermie.
