I purchase the Jack’s 321 the mixing ratio is as follows
By weight (add to one gallon of water):
- Weigh and completely dissolve 3 grams Jacks 5-12-26
- Weigh and completely dissolve 1 grams Magnesium Sulfate
- Weigh and completely dissolve 2 grams Jacks Calcium Nitrate 15.5-0-0
I I calculated that for 36 gals of water.
Jack’s (A) 3/4 cup
Jack’s (B) 1/2 cup
And © Epsom salts 1/4 cup, this is just by about 3 tbsp
Is this right? For 36 gals of water.
1st weight Jack’s (A)
2nd weight Epsom salt
3rd weight Jack’s (B)
