Say what you will, Clarence, I've got a couple of plants that don't produce like they used to, and whose hermie tendencies have become more pronounced over the years to the point that they are being replaced as we speak. The Diesel Maui Dawg x Hazy OG in particular...
Maybe you guys haven't led lives of constant crisis and upheaval like I have. Those mothers (at this point, probably 5th gen clones off the original plant grown from seed) have been 95% dead any number of times, and I believe the abuse has left its mark.
Regardless of what may have caused these changes, changes there have been. There's another thread around here on this subject (can't find it for you, my internet's too slow) wherein someone said, if I remember right, that sometimes things that are commonly interpreted as genetic drift are actually just a trait of a given plant that took X years to show itself, because it's genetically hardwired to do so.
It seems to me this becomes more likely with plants like the ones I've mentioned, which I got from a pollen chucking neighbor who makes seed each year for next year's crop. These were not strains that were carefully dialed in over years of growing out populations and making selections, and are therefore likelier to have unwanted traits that show themselves at apparently random intervals. Right?
