Fertilizer/Nutrient Cost breakdown

Fertilizer Costs as per manufactures suggested dosage and Current price as of January, 2019.

I'm going to stick with hydroponic formulas to make it easy and to help us get a generalized idea of prices.
I will also keep the quantities/prices similar as one trying a new nutrient should not buy the biggest quantity available.

(Since this line is expensive AND doesn't call for either in the separate stage as well as I cannot find a complete 4 part set I will do them separately using 4Week Veg/8Week Bloom MSD averages)

DISCLAIMER.
These were all calculated using the MSD(Manufactures Suggested Dosage) on their respective feeding charts.
Averages were obtained by adding the high end of the suggestions and dividing by the weeks they were used.
Those not stated as averages were calculated when over 75% of the dilution rates were the same dosage.
Most cost averages were calculated as if each were used equally unless otherwise stated, this was assumed that the cost of the set over the period of the grow was used completely so rates may actually be higher than actual costs if accounted for unused nutrients.
Costs were calculated on the high end to account for heavy feeders and high c02 situations.
Prices were all based off of Amazon, if you prefer your local grow store just replace $ with your cost.
Bloom nutrients are expected to run out first and be used the most, these calculations would be more accurate assuming an 8 week vegetation period.
Only liquid nutrients were observed for the purpose of justified nutrient ratio and calculation similarity.
Veg and Bloom truly should be calculated separately but considering someone trying a set will buy a trio, this guide will provide costs to run nutrients on a trial basis and will they most likely buy the "Trio" or "Bundle" as well, a majority of these lines call for some of the veg in the bloom stage and bloom in the veg stage such as Advanced nutrients, Fox farm, Botanicare as opposed to some such as the Canna line where nutrient lines are switched abruptly.
The basic formulas used are;
A/B=C
D/C=E
Where;
A is the entire contents of the bottle.
B is the recommended Dosage
C is the maximum Gallons if used at the rate of B
D is the cost of A per Amazon
E is the price per gallon of solution if used at the rate of B
