Some Useful info from the JR Peters site on how to make their stock 1 to .67 ratio base solution and how to amend it to your plants needs.
.....Just in case you don't want to make 1000 gallons.....
.....I crunched the numbers with their proportions to make 5 gallons.....
18.2g Jacks
1.4g Mg(optional)
12.4g CalNit.
Made a batch following ppm (.5 scale) as I went...
Jacks = 540 ppm
skipped the epsom
CalNit = 320ppm
Giving a nutrient solution of 860ppm (not including 130ppm of tap water) which is about 200ppm higher than what everything generally gets in veg. This is also the 1 : .67 ratio that Jacks calls for as a base. But I know from experience that my plants in veg will show purpling stems and some cal def at these numbers so I bump up the Calnit and feed at about 650ppm those troubles along wth slow rooting clones....go away. YMMV

Controlled Environment: Growing hydroponically with Jack’s
General Hydroponic growing with 2 part
Jack’s Professional Hydroponic Formula has been designed to serve as a base foundation for hydroponic growing. It can be manipulated in such a manner as to provide virtually any combination of nutrient levels desired, providing the highest availability to plants, due primarily to Jack’s proven ability to remain in true solution over long periods of time.
Jack’s Professional 5-12-26 Hydroponic
Follow these steps to obtain a precipitate free solution
Dissolve 130 ounces of 5-12-26 Hydroponic in 1000 gallons of final feed solution. You will obtain the following elemental PPM concentrations:
Element N P K Mg SO4 Fe Mn Zn Cu B Mo
PPM 50 52 215 63 246 3 .50 .15 .15 .50 .10
For the most effective use of the Hydroponic formula, it is essential that the nutrient content of the irrigation water being used is known. These figures are then taken into consideration and should be added to the distilled water figures as quotes above. This is of special importance when figuring the need for adding more Magnesium (Mg) and Calcium (ca) depending on the needs of the crops being grown.
Dissolve any additional Epsom salts desired into the above 1000-gallon solution before proceeding. For most crops, 50 PPM Magnesium is an adequate level in solution. To increase your Magnesium levels, dissolve 10 ounces of Epsom salts in 1000-gallons of final feed solution to obtain 7.5 PPM additional Magnesium and 3.00 ppm Sulfur (SO4).
IT IS ESSENTIAL THAT ANY EPSOM SALTS TO BE ADDED MUST BE ADDED TO THE HYDROPONIC SOLUTION AND BE DISSOLVED BEFORE THE ADDITION OF CALCIUM NITRATE.
NOTE: Jack’s Hydroponic fertilizer contains NO calcium.
After dissolving Jack’s Hydroponic and any Epsom salts in the tank, proceed as follows:
Dissolve 86 ounces of Calcium Nitrate into the above 1000-gallon solution to obtain a total nutrient concentration of 150 PPM Nitrogen and 116 PPM Calcium.
Should higher Nitrogen and Potassium levels be desired, the addition of 1-ounce Potassium Nitrate per 1000 gallons will add the following concentrations:
Nitrogen—1.00 ppm N Potassium 2.74 ppm K
Should higher Calcium levels be desired, the addition of 1 ounce Calcium Chloride per 1000-gallons would add the following concentrations:
Calcium as Ca—2.09 ppm Ca
Should higher Potash levels be desired, the addition of 1 ounce Potassium Sulfate per 1000-gallons would add the following concentrations:
Potassium as K—3.11 ppm K
Should higher Manganese levels be desired, the addition of 1-ounce Manganese sulfate per 1000 gallons would add the following concentrations:
Manganese as Mn—1.87 ppm Mn
Should higher Iron levels be desired, the addition of 1 ounce of the following per 1000 gallons will add the following concentrations:
13% Chelated Iron as Fe EDTA — 0.975 ppm Fe
11% Chelated Iron as Fe DTPA — 0.80 ppm Fe
6% Chelated Iron as Fe EDDHA — 0.45 ppm Fe
Jack’s Hydroponic Formula is heavily buffered to produce an idea working solution pH of between 6.00 and 6.50, but under unusual circumstances, it may be necessary to adjust the solution pH up or down with the use of mineral or organic acid complexes. Please consult water quality when choosing amount for pH change.
