Using none might be your best bet. Foliar feeds are unnecessary for most veggies (unless showing immediately correctable deficiency) and peppers aren't high nutrient feeders to begin with.

Foliage Pro 9-3-6 is a soluble liquid fertilizer, not a Foliar spray.

Foliage Pro is fairly low...114 ppm Nitrogen from what I recall, and that's lower than a lot of folks recommend. Moreover, it's in a 3:1:2 ratio, which means that it provides nutrients in a ratio close to that which the plant is actually using...without all that excess P and K (down the drain).

I was feeding 1.5 teaspoons per gallon, weekly. Last Friday, I dropped it down to 1 teaspoon. I'll hold it at 1 teaspoon, unless I see yellow lower leaves. If that happens, I'll probably increase the frequency of fertilization and just decrease the dose slightly.
