How To Calculate Npk?. Dry Salts

[Jokefox]

So i have a few different dry salts
And they all have different npk.

I took the recommended dosage and wieghed them so i have there weights.

How do i add them together?
Edit: all things are for 1 gallon
And how do i apply in the formula if i hald or quarter a dosage?

Jacks hydro -3g 5-12-26
Cal-nit- 2gs 15-0-0
Silicate powder 1.2g 0-0-5
Sulfer 1g. 0-0-50
Mpk 1.5g-3.0g. 0-51.5-34

Thanks for any help :)

there is a canna calculator that you can plug your inputs into by weight and it will give you ppm of each element
you can then add them up
then you know where you ppm's of all elements are and that way you can adjust as needed

Howdy, I think you had a thread going asking about 321. Just as a heads up, that is by volume and not weight, 3 parts jacks 2 parts calnit and 1 part Epsom. I believe they updated the 5-11-26 formula so it has a bit more magnesium than when 321 came out, strain dependent...but a full 1 part of Mg is no longer needed. I go with a half tsp of the jacks and calnit and a small pinch of Epsom per gallon of water during veg and then something closer to 3 parts jacks to 2 parts calnit during flower and slowly drop the level of calnit over the duration of flower.

Silica supplements are great, cut those out around mid flower though. I would drop them around the time you run the pk boost.

Jacks 321 is by grams.
If im wrong please cite a source that says so.

Not sure if I can link directly to it, but over at icmag they have a thread called "a question for growers using jacks 5-12-26. I think that guy delta9 is who popularized the mix, or at least as where I first heard of it.
