IMHO plants grown from colchcine treated seeds probably should not be consumed. Those plants are only good for seed prodution not consumption, and is why this method is used by some commercial seed producers. I'm honestly unsure what the pros or cons might be of clonning directly off a plant that's seeds were treated.
And yes, stressing the plant to make it turn hermphodite produces female pollen that can be used on other plants (how I learned) to produce femmed seeds. Plants grown from these seeds will not be prone to turning hermie any more then the original plants the seeds came from. In fact if you only have one plant to produce seeds and you herm it and self pollenate it, those seeds even will not be any worst then what it came from. All mj plants will herm for self presavation of the strain, some just do it easier then others.
