With the abundance of strains and hybrids out there. And splicing of those. That can and does create instabilities in itself. Or rather bring out what already existed in a strain originally. That just made it more prominent.
IMO its very strain dependent. Then after factoring in about a million outside variables. And less than admirable harvesting habits (such as harvesting at the point of trichome degradation ,
What I won't agree too is that all plants behave similarly.
I accidentally let plants go well past that point, and got them to harvest in November while snow was on the ground and they long stopped growing at all. I don't recall seeing a single seed in those buds. Thats limp proof. Hardly enough to base such a claim off of. But it could of gone either way but didn't.
I'm a science and data kind of guy. To believe that would cause every female to hermie Id need to see proof by some numbers.
Id never have to worry about it anyhow. I like clouds, lots and lots of clouds.
