I'd harvest the plants that are ready, but leave a stump (6" or so per plant) with some undernourished buds on each so the roots have something to do other than die and rot. A few buds with small leaves should continue the growth, but keep an eye out for new nanners. This might gain you enough time to finish the mom.

Selective harvesting may stress the mom again and compound the issues. I'd leave her alone and look carefully at her buds for additional nanners every once in a while.

The hairs (pistils) are turning red either because they are past their maturity, or it has already pollinated the embryo in the calyx....or because they have been damaged by wind, heat, breakage...

Since they are so close that the roots are intertwined, if one is pollinated they all are pollinated to some extent. (welcome to femmed seeds, btw)
