Oops, forgot to say that I intend to use these products for veggies (tomatoes, peppers, etc.).

Thanks!

They assume you will be using a metered application system and they are made to apply the appropriate amount per square area. These metered application systems usually have a dial that allows you to set the application rate.
Granted they should not make that assumption.

Thanks, kimmsr. I will have to dig around and see if I can find at what rate they should be applied. Most fertilizers I have used in the past had already put that info on the bottle.

So I have been looking quite a bit and have not found much info about this with these two products. Anyone else have any suggestions or thoughts?

If not, I will just start out slow, and gradually increase depending on how the plants are doing.

I'm not sure where the "assumption" that this was intended to be used only with a metered application system comes from. And the application rates are clearly called out on the website, if somewhat vague......"Outdoor Plants: Use 1/8 Cup (1 fl. Oz.- 1:128) per gallon of water. Feed vegetables, flowers, trees and shrubs every 2-3 weeks. Apply until soil is saturated or as a foliar feed until leaves are wet, top & bottom. It is best to foliar feed early or late in the day."

The emphasis is mine. I would use first as a soil drench before the suggestion of a foliar feed as that is a rather inefficient way of delivering nutrients. While plants do absorb some nutrients via leaf stomata with a foliar spray, they are much more adept at doing so through the roots. A granular organic fertilizer may be a more effective method, as they will break the application down to #'s per square foot.
