increasing potency through pollination

I pollinated a female killing fields f2 reg. and a feminised skunk with a male killing fields f2
resulting in

killing fields f3 producing 60% female to male ratio- grows out small but decent purple bud /mellow potency

skunk producing 70%+ female to male ratio- grows out small with large pistils /very low potency

Does anyone have any tips on how to increase potency and or size to increase yield?

I have female clones of mad scientist and blueberry.
Also AFGHANI seed regular which I am intending to grow to use to either pollinate or fertilise
I could also access kill fields f3 male or female to use in seed production male or female

regards

Just from what i have read this is the reason why most breeders spend a life time looking for a good male and then you see that male used in everything.

breeding takes time. to me its kind of a hit or miss like whatstrain said it can take a life time to get stable genetics. but you may come out with the next northern lights or white widow. do some research an see what you find, theres so much to learn like how to make an f1 hybrid and inbreed genetics and just well so much stuff.
