2.5 grams Jacks
2.5 grams Cal Nit
1/2 gram epsom salt
1tsp Dyna Gro Pro Tekt
if I'm right about this it should give me ppm of
N P K Ca Mg S SI
135 35 190 125 59 61 90
how does it look and any suggestions
oh yeah I'm gonna wait on the Fulvic Acid untill I get this worked out Thanks
hi, mixing equal weight is wrong. their instructions show several ways to mix it.
they recommend equal volume.
however, as snook mentioned, the best way to mix is by ec or ppm.
you also won't need any magnesium sulfate, the base formula has over 6% magnesium.
i'm going to assume that you don't have a meter and that's why you are talking about mixing by weight.
if you take a 1/4 teaspoon plus a 1/8 teaspoon of each, 3/8 teaspoon total of each, you will get approx 750 ppm or ec 1.5. this is per gallon.
if you do have a meter, you don't need to measure water volume.
600 ppm is 360 ppm jacks and 240 ppm calcinit 240/360=.67
750 ppm is 450 ppm jacks and 300 ppm calcinit 300/450=.67
900 ppm is 540 ppm jacks and 360 ppm calcinit 540/360=.67
i cannot imagine a situation where you will need a solution stronger than this.
i have grown a 22.5 oz plant in a 3.5 gal container of coco with 600 ppm for life with no displays or problems, no additives or boosters or even ph adjusters.
if you mix it properly you won't have any ph issues.
the ratio is 1/.67 jacks/calcinit
