HERMAPHRODITES AT END OF BUDDING

[Rusty Trichome]

When it decides to start budding again, is the lower half more than likely going to be well matured, and possibly produce male pollen?

Doubtful, but I doubt she appreciates you cutting of her cola. But since you're re-vegging her anyway, it shouldn't be an issue. I wouldn't do that half way through flowering if you were going to continue flowering her though. That kind of stress can produce nanners.

and from what i've heard a plant that polinates itself wont produce viable seeds??

A plant CAN pollinate itself with it's own pollen. If allowed to mature, the seeds will be viable and 100% female. (unless a true male is around to screw things up)

and if this female with male flowers pollinates another female, the seeds will be feminized?

Yup. But you should start with stable genetics to avoid hermaphrodite issues further down the line. (successive generations)
