14/10 @ last two weeks of flowering?

[knna]

Im a bit confused: i thing some people answer about 10/14 and others about 14/10 (lights on/off).

I use both. 10/14 at the beggining and 14/10 at the end. And yes, i note it in the potency. Only slighty more yield than 12/12, but i think it improves THC %.
