Since @Skitty kept asking for this one and its easy enough, might as well put it up here
Botanicare CalMag+ is 2-0-0-3.2Ca-1.2Mg-0.1Fe
@ 5ml per gallon, this will produce
26ppm N
42ppm Ca
16ppm Mg
1.3ppm Fe
We will reverse engineer this, but using magnesium sulfate (epsom) instead of nitrate, and using a 10-11% FeDTPA
As a direct tank mix, per 10 gallons:
8.4 grams Yara Calcium Nitrate
6.1 grams Epsom
0.5 grams FeDTPA
This technically is not compatible as a stock solution, because Ca and S in the same concentrated solution will precipitate, especially if trying to copy the same concentration as Botanicare. USER BEWARE: If you wanted to make a less concentrated solution with the same Ca-Mg-Fe ratios, you would have to go at about 30ml/gallon and mix the following into a gallon of stock solution:
106g Yara Calcium Nitrate
77g Epsom
7g FeDTPA
Or you could multiply these number by (6) and keep the Epsom separate, in its own gallon jug, and use both at 5ml per gallon.
