I know a lot of people, including myself, use fish fertilizer. I use a brand called Alaska fish fertilizer. You can find it at Lowes. It's about 8 dollars a bottle. I also use miracle grow once every 3 to 4 weeks. I haven't fertilized as much this year though, because it has rained so much. Good Luck!

I'd actually prefer the stuff you're using during flowering and podding than the MG AP(24-8-16) and fish ferts(5-1-1) I use.

P and K are much more important than N for fruiting.

I say stick with it until you're not happy.

I agree with woohooman, if you are happy with what you are using, no need to change. I generally used a balance fertilizer like 8-8-8 or 20-20-20, and only modify if the plant shows something wrong. If leaves yellow, I would probably up the nitrogen, but you really have to be careful with that or you could end up with huge leafy plants and few peppers. Phoshorus (middle number) promotes flowers and fruit, so you don't want to skimp on that when plants are fruiting. Your 9-12-12 is a good choice.

I do support Kevin's opinion of "P and K are much more important than N for fruiting"

Good subject, thanks.

I stick with equal NPK ratio from seedling through fruit in aero..

I have changed ratio as an experiment and noticed no difference in growth or fruit.

Thanks for the wisdom guys ! Gonna stick with the 9-12-12 !!

Yep, as Willard says, it doesn't make much of a difference.
Even during fruiting, plants use much more Nitrogen than P or K. So as long as there is adequate P and K, all should be well.
