https://www.rollitup.org/hydroponics-aeroponics/268790-lucas-formula-recipe-scratch-really.htmlBased on the 16 essential elements, his wonder fuel is far from complete. You tell me what his NPK and micro values are, and I'll show you how this formula was developed by a newb for noobs who don't know squat about plant nutrition.
I want to see your plants just before harvest.

Based upon the most recent analysis of Floramicro and Flora Bloom this is the corrected formula for the Luca Method:
ppm concentrations at a 1:100 dilution
Nitrogen 167
Phosphorus 333
Potassium 397
Magnesium 100
Calcium 215
Sulfur 133
Iron 3.33
Manganese 1.67
Boron 1.67
Zinc 1.00
Copper .33
Molybdenum .03
Ounces
PART A
Calcium Nitrate 14.2
Iron Chelate .45
Ounces
Part B
MonoPotassium Phosphate 21.0
Magnesium Sulfate 13.5
Manganese Sulfate .090
Boric Acid / Solubor.123
Zinc Sulfate .058
Copper Sulfate .020
Ammonium Molybdate .001
Volume of Stock Solutions 1/2 gallon each part
Dilution Rate
100
This is a high concentrate formulation based upon analysis concentrations. The EC of the Part A is 1.08, Part B EC = 1.64, combined the EC is 2.72. Obviously a higher EC then most would consider using.
The PH used with RO water should be 5.4 at 1:100
The TDS ast a 1:100 mix is 1904
