More interesting nutrient related charts...
I found the second one interesting because the 'pounds per acre' numbers and ratio look remarkably similar to 'part per million' numbers in nutrient solutions...

I would absolutely love to see a similar chart of cannabis strains and pounds of element per acre...

Hehehe... Charts-R-Us...

Also, of particular interest to me in the second chart of post number 11, are the ratios of Ca to Mg... It is often stressed by people who are picky about nute ratios, that Ca to Mg should be no less than 2:1 and higher ratios are often prefered...
In reviewing the charts I note ratios from 5:1 to 1:1.56...
Average ratio across the chart is...
N : P : K : Ca : Mg : S
7 : 2.5 : 9 : 1.9 : 1 : 1

Also in reference to the table in post #11...

To achieve an optimum hempyield, twice as much nutrient must be available to the crop as will finally be removed from the soil at harvest. A hemp field produces a very large bulk of vegetative material in a short vegetative period. The nitrogen uptake is most intensive the first 6 to 8 weeks, while potassium and in particular phosphorous are needed more during flowering and seed formation. Industrial hemp requires 105 to 130 lbs./acre (120 to 150 kg./ha) nitrogen, 45 to 70 lbs./acre (50 to 80 kg/ha) phosphate and 52 to 70 lbs./acre (60 to 80 kg/ha) potash.

I've edited a bit more info and some of the charts into the original post.
