Plants went to seed, why?

[EvilCartman]

Am I right in arguing though that it was NOT letting them go longer that caused them to go to seed, but more probable some sort of stress caused one to hermie and that got the whole crop?

We'll never know...
Are the seeds mature?
If the seeding was the result of a late-flower hermie episode, then I would expect to see a lot of immature seeds.

He's insisting they were too old, but I dont' think they were and I'm damn sure that wouldn't have caused the plant to go to seed... WOuld having them flower too long make them go hermie?

Many strains do this as they ripen-up. Survival technique, and all.
If the genetics are questionable, it's anybody's guess as to if, when, or how bad.

THis has been an ongoing battle, he likes to cut them down too soon, and it ends up being harsher (imo) This was the first crop I actually made him watch the tricomes and go by that color other than what some stupid calendar said and then this happens...

How long was your partner intending to go, 8 weeks?
If there are mature seeds, then the "event" didn't occur in the final week or so.
