raw salts in dwc, need help

im basically wanting to recreate general hydro's maxigrow/maxibloom. it's a 1 part nutrient that has everything except silica in powder form, adding 1 tsp per gallon give you 1.7ec..
ideally i want to create a base. like one part that is the same for both veg and flower.. then a veg additive and a flower additive. so by adding the veg additive to the base the end result is 'maxigrow' and by adding the flower mixture to the base, the end result is 'maxibloom'.
here is the info for maxigrow:

maxigrow (10-5-14) is a pretty complete one part powder with the exception of silica. here's the percentages according to the bag i have:
Total Nitrogen: 10%
- Ammoniacal Nitrogen: 1.5%
- Nitrate Nitrogen: 8.5%

Phosphate (P2O5): 5%

Soluble Potash (K2O): 14%

Calcium (CA): 6%

Water Soluble Magnesium: 2%

Combined Sulfur: 3%

Chelated Iron (Fe): 0.12%

Chelated Manganese (Mn): 0.05%

Derived from: Ammonium Molybdate, Ammonium Nitrate, Calcium Nitrate, Calcium Sulfate, Copper Sulfate, Iron DPTA, Magnesium Sulfate, Manganese EDTA, Monopotassium Phosphate, Potassium Borate, Potassium Nitrate and Zinc Sulfate.

here is the info for maxibloom:

MaxiBloom (5-15-14) for comparison:

Nitrogen: 5%
- 0.5% Ammoniacal Nitrogen
- 4.5% Nitrate Nitrogen

Available Phosphate (P2O5): 15%

Soluble Potash (K2O): 14%

CA: 5%

water soluble Mg: 3.5%

Sulfur: 4%

Iron: 0.1%

Derived from: Ammonium Molybdate, Ammonium Nitrate, Calcium Nitrate, Calcium Sulfate, Copper Sulfate, Iron DTPA, Iron EDTA, Magnesium Sulfate, Manganese Sulfate, Monopotassium Phosphate, Potassium Borate, Potassium Nitrate, Potassium Sulfate, and Zinc Sulfate

ok, so the questions i have are, what does the percentage actually mean? does 5-15-14 mean 5ppm-15ppm-14ppm? or? and how would i recreate this formula. i assume the 'derived from' portion on each bag is the salts they used to achieve their mix.

i tried using this excel spreadsheet 'saltmix3b' that calculates nutrients. i used the ingredients listed on both bags, and i got it pretty close, but i had to add a couple extra things to get what i think is the same ratio. im probably not doing it right though.

so on the spreadsheet. ill upload them if anyone can look, but here's the copied over values:

base:
ammonium nitrate pure (nh4no3): 0.55g
calcium nitrate (ca(NO3)2): 7.8g
Calcium sulphate dihydrate (CaSO4.2H2O): 0.8g
Magnesium sulphate (MgSO4): 3.95g
Monopotassium phosphate (KH2PO4): 8.5g
Potassium Nitrate (KNO3): 3.9g

veg add:
ammonium nitrate pure (nh4no3): 3.15g
calcium nitrate (ca(NO3)2): 1.8g
Potassium Nitrate (KNO3): 4.1g

flower add:
Magnesium Oxide (MgO): 0.5g
Magnesium sulphate (MgSO4): 1.55g
Monopotassium phosphate (KH2PO4): 5.5g
Phosphate (PO4) 8.5g

HOW MUCH TRACE MINERALS?? SILICA?? HOW MUCH TABLE SALT?? (sodium chloride)

need to divide these values by 10

...

can anyone offer me any advice on how to recreate maxigrow/maxibloom using the 'derived from' ingredients please? or any other advice or anything at all is appreciated

This is way too complicated man, nobody is going to go through all that for you and be able to reproduce that for you. Fall off your wallet and by the maxi grow. Or just mix macros at 2-1-3 for grow ooooor 1-3-3 for bloom, and add micros.

i already do buy it and its cheap its not about the money. it's about preserving a product that im concerned might change with GH recently selling the company.

Download hydrobuddy and use that to make formulas. It's better than using a spreadsheet, and has accurate calculations.

The numbers in NPK are percentages by mass. ppm is mass concentration measured in mg/L

You don't need any sodium chloride. You will need a source of iron.

I'd stop worrying about trying to copy GH and use one of the formulas built into the hydrobuddy database, or hoagland solution as a starting point.
