I was bored this morning and did some calculations to help me decide which nutrients to use for my next grow. Thought one way to compare was to determine the cost per gallon. I followed the hydro schedule for fox farm and advanced nutrient getting 2 values. 1 for the first week and 1 for the last to give a range of the prices per gallon.
(These values are per gallon so multiple them by your reservoir size to determine the cost per reservoir change) Also this does not compensate for the cost of RO water you'll have to figure that out yourself.
Here goes:
Fox Farm Using Quart Prices:
.37-.46 per gallon according to the rations in their feeding schedule here:

(please note this does not include their solubles because they sell it by the pound and you use it by the teaspoon. I'll have to weight it to find the density so I can calculate the cost per teaspoon.) I'll do that soon enough
Advanced Nutrients (they have so many so I did the least expensive one and the most expensive one)
The pricing is by the Liter
AV Grow Micro Bloom Base At Hobbyist Level
1.39-7.77 per gallon according to schedule here:

Av Connoisseur at the "Grand Master Level"
$2.7-$13.63 per gallon
Lucas Formula at Quart Prices:
.15-.24 per gallon
