A question before I comment, if you please. What's more important to you - easy and reliable delivery of nutrients or an 'organic or nothing' ideology?

tapla - I'm an easy and reliable man for sure.

You won't have any trouble with over-fertilizing using that product. You could probably pour it on undiluted and not burn the plants (obviously not recommended, but just sayin'). The couple drops you're using is not enough though either, I'd go by what the label says.

Soluble fertilizers like MG, Peter's, Foliage-Pro, others ... provide nutrients in a form plants can (and do) take up as soon as they hit the soil. You can purchase them in the ratio in which plants use nutrients, and apply them ass needed/when needed, and be sure plants are getting them ass needed/when needed.

Nutrients from organic sources depend on populations of soil biota to break nutrients down into elemental forms before they can be absorbed by plants. Because these populations are dependent on a variety of cultural conditions, there numbers are very unstable - boom or bust, which makes delivery of nutrients from organic sources in containers erratic and unreliable. You may apply your fertilizer today, but there is no guarantee that the nutrients locked in hydrocarbon chains will be available today, next week, or even next month.

Skip any fertilizer with a middle number higher than either the first or third numbers. I pay pretty close attention to results and yields, and I've been happiest with fertilizers that provide NPK in a 3:1:2 ratio. These include 24-8-16, 12-4-8, and 9-3-6, with the Foliage-Pro 9-3-6 getting the nod because it supplies all the essential elements in the right NPK ratio AND in a favorable ratio to each other.

Good luck!

very helpful, thanks. It makes me think...

Actually the Fox Farm concentrate is quite powerful and capable of causing a burn, not sure exactly how going by the analysis. I'm going to stick with the organic method for now, its working...
