Yo Yo Yo.
Hahahhahahha.
Im sorry my man but it could be way better for you
.
u can't really do nothing as far as pistils because autos have their own life cycle and by this i mean u cannot control(Reverse) them with 18/6 vegetative cycle.
So just let them finish.
And since autos have a short life cycle u need to start strong to have a good yield in the end.
My man the seeds u had were good.
I think your problem was the soil u were using...
Im sure next time u will do way better...
If you use feminised seeds don't forget to plant in a huge pot....
the bigger the pot the better the yield.
But as for autos we go with more pots(small ones) better yields...
