New Grower But when do they die off completely?

[madmable]

seeds may mature, the only issue could be genetics and thats luck, seeds will take from the parent plant, meaning they could be more liable to hermie as the mothers did, but on the other hand you could be lucky and end up with alot of viable good seed! worth a shot, try cutting nutes out a little to prolong as these can often cause leaves to brown and fall of, but she should go 20+ weeks,seeds should only need 2 or 3 once started! keep us posted on any seed and if its viable!

Done this with photoperiods a few times on different strains. No hermies this way as long as there are balls (not nannas) involved.
No "both parents" involved. Think cloned seeds.
They'll all be fems.

The Onyx has / had one branch that probably was hit with overspray at one time. It grew nannas and not balls. Removed and now should be good for fem'ed auto seeds on the rest of the plant.

That would be on a selfed seeded plant.
Pollen used on another would be having genetics from both involved. That could be good depending on purpose or course taken.
