I was wondering if anyone on here has any experience making a premade stock solution of the jacks hydro, epsom, cal nit? I wanted to just have a stock on hand and add as needed if possible I can’t find anything on any mixing ratios. Thanks amigos!
 
Is there a way to use the hydro buddy on your phone I only saw options for downloading on a computer for windows and Linus? Thanks that’s exactly what I was looking for though appreciate the response amigo.
It's discussed in this attached icmag thread
 
I make stock with jacks, calnit, and MgSO4 at a 1g:10ml ratio. Could go double or triple, maybe more, but it makes for easy mixing and math. A 3/2/1 would be 30ml/gal,20ml/gal,10ml/gal. I use 20/15/7 +silica in my coco dtw growing trees

Question for you so to make stock solution of the jacks hydro plus Epsom and cal nit
What is the exact mixing amounts for each also can I mix the 5-12-26 with Epsom and cal nit by itself

In general, it's like this:
3.6 grams per gallon of jacks
2.4 grams per gallon of cal-nit
1.2 grams per gallon mag sulfate
But in practice, you need to see what your EC is once you mix that up in your water. It would be fine to mix to that strength, then dilute until you hit your desired EC.
