Hey crys...nice to meet the dude that started the NPK-Ca-Mg nomenclature. Who would have ever known Ca and Mg were important without you.
is this the alkcalc you seek?

or this one:

Should we have a contest to see who can post the earliest recorded usage of the N-P-K-Ca-Mg nomenclature?
Hey YS, I don't know if it was this thread or another but you recommended amending peat with CaCO3 opposed to dolomite, and spurr earlier here opposed perlite for aeration amendment..
Can I get some clarity or reasoning behind this?
FWIW.. Plan to use the standard 3/2 jacks/calnit in premier peat w/ dechlorinated tap..
Which is exactly why i started our interaction off with saying that it seems like you lack any introspective powers. Its pretty obvious by the actions of others (voting, snide remarks, private messages) that im not the only one that took your message as cocky & disrespectful to spurr. Perhaps that's not what you were going for, but its what we got from it. Tone is often lost in translation on the internet, everyone's guilty of being misunderstood at some point on a forum. Just recognize that there seems to be a disconnect between the way you think you're conducting yourself and the way others are interpreting your behavior.I don't share your view that I "berate" him, or have a "f*ck you" attitude.
Potter is an interesting author, ive read everything that hes put out. I doubt you'll find it that valuable of information if you didn't find the Coffman and Gentner papers valuable, there's pretty much zero unique conclusions that the paper draws (i.e. no new info), but that doesn't take away from the quality of it. Most of the experiments have only 10-20 plants per group (not hundreds) , and cloned plants had hugely different physical characteristics although similiar secondary metabolite ratios (meaning the test groups weren't that homogenous). BTW the thesis is not about increasing THC production, its about "improv[ing] the reliable production of phytopharmaceutical feedstock for the production of botanical medicines from Cannabis sativa L." GW Pharma cultivates several high CBD strains that have no detectable levels of THC.I read both of the papers as soon as you posted them. While I didn't find them valuable, it did lead me to find a paper by GW pharma - google phd_david_potter. 225 pages. No, I haven't read it in its entirety yet. Its method makes me more confident to lean on its results - hundreds of clones per experiment. And its thesis IS to increase THC production.

@ iSMOKE.KUSH,
Nope, I didn't list the order to use each compound in this thread, great point. I listed that in the screencast video, but I forgot to do so here, thanks for pointing that out. Here is the relevant info:
(when not wishing to use Bru'n Water or UNH AlkCalc or HydroBuddy)
For direct addition to 100 liters:
(see this post: https://www.icmag.com/ic/showpost.php?p=4707360&postcount=2)
1. fill reservoir with 95% of the volume of water neededFor stock solutions:
2. add potassium carbonate for veg, early-flowering and full-flowering. Default amount for RO water is 0.096 g/L (make sure to pre-dissolve it in some water, then pour it into the reservoir)
3. add potassium silicate, as AgSil 16H it's 0.324 g/L for veg, 0.405 g/L for preflowering and then some ('early-flowering' stage), and 0.356 g/L for later-flowering.
4. add citric acid at 0.024 g/L for veg, early-flowering and full-flowering. If the pH isn't 7.0, then add more until it is 7.0 (make sure to pre-dissolve it in some water, then pour it into the reservoir).
5. add 0.081 mL/L sulfuric acid (35% purity) for veg, 0.081 mL/L sulfuric acid (35% purity) for early-flowering, and 0.058 mL/L phosphoric acid (75% purity) for full-flowering (no sulfuric acid at that stage).
6. check pH and adjust if it's above ~6.3, use citric acid.
add fertilizer compounds (by weight) according to screenshots on page 1 (post #2).
7. start by adding calcium and magnesium rich compounds such as YaraLiva CalciNit and Epsom salt and magnesium nirate.
8. then add micro nutrient metals, such as FeDTPA, zinc, manganese, etc.
9. finally add fertilizer compounds rich in K and P. (the goal is to limit formation of P-Ca, P-Mg, etc., via citric acid affect the cations before P is added).
10. check pH and adjust if needed
11. add the remaining 5% volume of water
12. done.
(see this post: https://www.icmag.com/ic/showpost.php?p=4707360&postcount=3)
1. Make stock solutions A, B and C from screenshots in 3rd post of this thread (here). Notes on correctly making stock solutions can be found in the download from my web site and found in this thread (here).
2. fill reservoir with 95% of the volume of water needed
3. add potassium carbonate for veg, early-flowering and full-flowering. Default amount for RO water is 0.096 g/L (make sure to pre-dissolve it in some water, then pour it into the reservoir)
4. add 10 mL/L of stock solution C for veg, 10 mL/L of stock solution C for early-flowering and stock solution C for full-flowering.
5. add citric acid at 0.024 g/L for veg, early-flowering and full-flowering. If the pH isn't 7.0, then add more until it is 7.0 (make sure to pre-dissolve it in some water, then pour it into the reservoir).
6. add 0.081 mL/L sulfuric acid (35% purity) for veg, 0.081 mL/L sulfuric acid (35% purity) for early-flowering, and 0.058 mL/L phosphoric acid (75% purity) for full-flowering (no sulfuric acid at that stage).
7. check pH and adjust if it's above ~6.3, use citric acid.
8. add 10 mL/L of stock solution A for veg, 10 mL/L of stock solution A for early-flowering and stock solution A for full-flowering.
9. finally add 10 mL/L of stock solution B for veg, 10 mL/L of stock solution B for early-flowering and stock solution B for full-flowering. (the goal is to limit formation of P-Ca, P-Mg, etc., via citric acid affect the cations before P is added).
10. check pH and adjust if needed
11. add the remaining 5% volume of water
