Mistake bro. A lot of the time, strains that herm on a seed run outgrow it by the second or third clone generation. I've been around a long time and have thrown out a lot of shit because of some nanners around 3-4 weeks. A few years ago I had a tahoe x sour d x chem d that was a KILLER, but it grew balls around 3-4 weeks. I kept it anyway because it turned out to be such good smoke. After the second or third clone gen it completely stopped herming. Since then, any herm plant I get that's extremely good smoke, I keep it for a bit and see if it outgrows the herming. 90% of the time it does. And I've gotten plants that herm before with not a single grain of pollen to be found. Keep that in mind next time you get a herm instead of freaking out and chopping. It could have had sterile pollen, no pollen, or could have outgrown it.
