Yes mate you can so please ignore all previously given kneejerk responses to hermies as all you have is a lone late nana showing on a finished plant which is perfectly natural and is not a sign of hermaphrodism.
Plants grown for sensi are themselves subjected to the stress of not being pollinated as they have to carry themselves in a virgin condition when in nature they would have been pollinated weeks earlier and its the response to this stress,the production of a few late nana's that you are witnessing.
Reveg the plant and grow her again and at most she'll produce a few nana's and that's it.
Hope this helps.
@noneedforalarm. It sounds like you have had a few stray pollinations from your hermie which is no big deal as a very lightly seeded plant still grows sensi but just not where the pollen landed but once you have a fairly good dusting you'll affect the whole plant as it becomes a seed bearer and its drive is more toward seed not resin.
