Making Your Own Nutrient Concentrates

HNY Wood!
 
If you want to emulate 321, the first thing is to program all the numbers from Jacks, CalNite and Epsom, then set the weights of each (3-2-1 grams) and compute. Here is the results of that (same pic from last page).

Had I used regular Ag Grade CalNite, the NH4 would've been a little higher, but that aside, you can see all of the numbers that came from that formula. What I do next is to copy all of the NPK-Ca-Mg and Si if applicable and jot those down as the basic formulation.

NO3 (nitrate)--------------------128
NH4 (ammonium)-------------1.6
P--------------------------------------41.5
K--------------------------------------171
Ca-------------------------------------124
Mg-------------------------------------76

From here I do my research, look at my plants and do whatever I need to get the best idea I can about maybe tweaking those numbers. I might wish to round up or down, or drastically change any one, several or all, whatever. Once I have targets I like and want to try, I remove the 3 parts involved in the 321 formulation and load up all of the profiles I have saved for each of the salt concentrations I have. Then on the main page of Hydro Buddy (or other nute calc) and input the targets I recently discovered/edited, then calculate and see how much of each of the salt compounds I need to achieve my targets, and that's it.

Maybe after some time I notice my plants are reacting good or bad I might want to further tweak the numbers, then just repeat the above process is all. Eventually you'll find what best works for your grow and judging by the way your grow now looks, I would emulate your current feeding program plus any tweaks your research leads you to desire. Eventually, you'll concoct a better formulation than your current program and as your soil chemistry changes, or climate changes, light changes etc etc etc, you'll be able to tweak as your needs dictate and your feeding program will always be very near or on par with your plants which is the whole point.

I think I’m going to go with Jacks 321 to start. I’ll amend nitrogen or Mag if the plants want more or less of those 2.

What is your current feeding program because your plants look fabulous and I'd like to see how 321 differs from what you're now giving them? I know it's Mega, but am not certain which of their 4 formulations you're using so mention what the NPK is on the label. Also which CalMag are you using and how much of it per gal? Any other ingredients with elements being used?

Calmag Pro
Nitrate nitrogen 13% ammonical nitrogen 1%
calcium 11%
Magnesium 3.5%

you said 3.5 grams of the Mega? How much calmag do you add to that?
 
Here's the 2 of them together. First your MC/CM regimen, 2nd 321.

Do you add each by measuring ppm instead of by measuring by weight?

The above 2 pics is me telling HB the weights and HB tells me what the results of each regimen is. The other way is me telling HB what results I want, and it will tell me the weights needed to achieve them. So if you wanted to make either of those with your salt collection, you first need to state which targets you want to hit. I can then input those targets, and after computing, it will tell me how much weight of each salt is needed. But because your salts are made into a 1:10 concentrate, you would merely shift the decimal over one position and read grams as ml of liquid.

Ok easy enough, I’ll look at the charts again.

yeah, just compare and consider what you like about each, factor in your own research or inclinations, then tell me what targets you want and I'll input your targets and post a screenshot of the results. Then all you gotta do is shift the decimal by 1 and multiply by how many gallons you want to make. BTW, just target the macros, secondaries and silica if you want to use that. I use 20 in Veg, 40 in bloom. Farside uses 50ppm Si all throughout. Some folks don't use any. Personal preference...
