It's not a very efficient way to make calcium water soluble, that's why calcium nitrate is the standard.

How's it do as a supplemental source of Ca? When using it in the math, the app uses it for about 35% of the Ca, cal nit adds the rest. Otherwise, do you have any suggested secondary Ca sources?

I just read this in a MaxYield article;
https://www.maximumyield.com/are-all-calcium-magnesium-supplements-alike/2/1263
What I got out of that is that nitrates don't make good foliar sprays.

I can get 50lb bags of calcium nitrate for $26.

Flipped today week 10, using 3.6 2.4 1.1, everything looking lush so far.
Can I use canna boost with jacks hydro?
(edit)also can I use pk 13/14 ?

What's wrong with the 3-2-1 ratio? You've just made the math a lot more complicated and once you dilute to your target EC, the exact amounts don't matter.
And yes you could but why would you want to? Just try running that mix straight through. You'll like it.

I couldn't find whether 3-2-1 was grams or spoons and found lots of conflicting info. Can't remember where I saw it but came across someone claiming those measurements I used in grams were the best. Plants love it. What measurement do you use for 3-2-1?
I weigh 360 240 110 grams and make a base stock of each in a separate pickling jar. Take equal measurement of each and add till I get target EC, so it's pretty straight forward
Just as a bloom boost and to put some weight on. I remember you saying you used mkp? Do you still use it or just the 3-2-1?

3-2-1 is a ratio, not a measurement. Always weigh your dry salts, volume is not reliable. Dissolve each ingredient separately- this is important because the sulfate in epsom salt and in the nutrient mix will react with the calcium in calcium nitrate and form calcium sulfate which is NOT water soluble and therefore not available for plants to use in a hydroponic setting.
Once each ingredient is dissolved, combine them and dilute to desired nutrient strength. Finally, balance pH if necessary before introducing the solution to your plants.

3.6-2.4-1.1 is JR Peter's recommended dosage, but the refinements of the canna community reduced that down to the much simpler plain 321. Both systems are measured in grams per gallon. Here are the PPM comparisons of both, GH, Megacrop, Skybound's mid bloom and a couple others. If you want to read my reasons to stop using Jack's, Peter's or every other blend, read THIS thread on 420 as I covered that I believe by the end of page one, but I won't try to deter you if you want to stay with 321.

I'm hoping someone can help me out with a calcium conundrum. Has anybody tried mixing calcium carbonate with vinegar to chemically strip out the calcium? The end result is called Calcium Acetate Ca(C2H3O2)2, and has the molecular weight of 158.16604 g/mol. I am hoping someone knows how to do the math to convert the molecular weight into mg/L(PPM)?

i like the sulfur in steiner's formula. i wonder which version of megacrop that is also? i expected it to have more sulfur.

Yeah, Steiner's sulfur ratio is racy. IDK if S tox is possible, but I imagine Mr Steiner knows, lol. Shooting from the hip, I believe I have the old blend of Mega in Hydro Buddy, but not knowing the differences, I forget what elemental differences to look for, but here's the analysis I used to formulate the solution.
After considering a few factors, I'm generally liking Steiner's too, though it would definitely need a bit of adjustment to work with canna. On 420 forums, I have a High Brix Hydro thread that is basically a succession thread of How To Use Hydro Buddy and Mix Concentrates, but basically, I am in search of the PERFECT hydro feed ranges, and in doing so I will also have elevated the brix levels due to producing very healthy plants. Anyways, in my studies I've learned that we (hydro growers) need to identify how much nitrate can safely be offered to our roots. The roots can tolerate more than what's needed, but if they have to tolerate more, they'll uptake more nitrate than what's needed and take less of something else. Also carbs and sugars will have to be burned up to safely process the excess nitrate which in turn lowers the brix and lowers the overall health. Steiner's K and Ca is also very high, but everything else I generally like. But at the end of it all, it's nice having all of these references to consider when formulating our needs for cannabis.

Oh yeah, I forgot, I found my numbers;

If you're gonna keep posting this chart, at least indicate on it what version of MC you're using. Also, the current MC formula has been shipping for almost five months and the label is on their site so you have no excuse not use the current formula. You should do so before declaring that MC is "garbage." Otherwise anyone paying attention is going to conclude that your analysis is garbage.
**edit: changed six months to five months

oh I'm sorry, I didn't mean to imply that I care about Megacrop's public relations. For the record, GH could have changed their formula and I still would not care. IN fact, "I" have changed my own formula, yet I keep "posting this chart". The chart was never intended to show a brand in the kindest of light, but rather to demonstrate for comparative purposes what different people and brands are using.

So I got bored today and went looking for Megacrop's new recipe, loaded the formula into Hydro Buddy and crunched the numbers and I gotta say, it looks a lot better than their former blend!
N is still high, but usable, P is in better range, but still low, K looks great, Ca lowered which isn't good, but it's about 2:1 with Mag so that's a plus. Sulfur is very low, but that's good because it's a horrible idea to put calcium anywhere near sulfates and this bag has both. I'm also not a fan of the high micro levels except for Iron and Manganese, but whatever. When considering all of the chelated elements they're adding, plus the MANY other organic inputs in the bag, I can now see why people are growing pretty good plants. I don't mean to say that with conceit, but look at everyone's leaves. Buds will get fat or frosty because of the strain, but the leaves and stems will say whether the plant likes the feed or just tolerates it. Jack's 321 does better than Megacrop IMO and also Skybound's blend does better than Jack's. Fortunately for Skybound, if he sees a deficiency or a toxicity, he can immediate adjust the elemental ppm targets in Hydro Buddy and Hydro Buddy will tell Skybound to use a slightly different mixture to get Skybound those targets Whereas Jack's and Megacrop users can only say "close enough for me", or a similar sentiment.

MC would look really good if supplemented with calmag and some epsom. Perhaps molasses also to get the iron content higher.

I just realised 3.6 2.4 1.1 is more or less 321 minus .1 on the epsom, doh! Its just when I was looking at skybounds chart thing, because it's comparing ratios to the gal, the ratios look so off. I've read over the thread a couple of times now and the whole things making a little more sense.
I could use a little more advice. I just got some mkp and on day 8 of flower, a few different ratios have been thrown about and not sure which to use and when to use them. I was thinking switching after 2 weeks of stretch? Theyre still loving the 321 though, chucking out pistols.
It'll be my first successful grow, so want to get it right. Would you carry on with 321, or use the mkp?
I've also been foliar spraying with some GH micros and silica, should I stop that now? Hydro shop has ordered me some bio genesis micros but when takes forever doing anythjng. Cheers
