if you have RESPECTFUL QUESTIONS i can explain why it works .

Ripening fruits and vegetables give off ethylene, a hormone that influences femaleness. Apple juice does not form ethylene as it degrades. So how does a foliar feed with apple juice influence female sexual expression?

ok for starters flowering a cannabis plant and producing seeds are different things. The cannabis plant flowers due to changes in lighting, vegetative growth occurs when lighting is 16-24 hours of light a day, and as the lighting changes it produces a flower. Indoor growers usually use a cycle of 12 hours continuous light followed by 12 hours darkness to induce flowering. For seeds to be produced the female plant must be pollinated by a male plant; however there are ways to stress a female into producing seeds without a male. Your method makes no sense and you have no scientific basis to back this claim up, and trust me I do not need any help in growing, I have been growing for many years, check this out this is one of my babies from this season my pics

You should do some research check this out its from this site how fem seeds are made

this clearly explains fem seeds are produced by female plants being treated with a chemical to produce male flowers, they take that pollen that is produced from the male flower and pollinate other female plants that produce what we call feminized seeds.
