I'd go with Jack's Hydro along with the Calcium nitrate. They offer a package price for both.
I was using Jacks along with the cal nitrate and epsom salt in the 3-2-1 formula that somewhat popular. Recently, I was given a more optimal formulation which I really like.
2.5 grams Jacks Hydro
2.5 grams Cal nitrate
.25 grams potassium silicate
.25 grams ammonium sulfate (first 3 weeks bloom)
.25 grams ammonium phosphate (weeks 4 through 6 or 7 or 8 depending on the strain)
All weights are per gallon of water.
Big thanks to dizzlekush for this formula. My plants are loving it. I run on bulk rockwool with hydroton in 4x4 beds. I can't imagine why it wouldn't be ideal with a chow mix of coco and hydroton once the coco is conditioned.
I've never used the MOST so I can't really give any useful information. I know Capulator has experience with that item.
As far as the Bloom Booster, I've used it a couple of different ways. I've added it at a .5 gram a gallon to my base nutrient during flower and honestly didn't see any difference overall.
Its my understanding according to the folks at J.R. Peters that the bloom booster is a one time, stand alone shot. No need to add the cal nitrate. I've used it this way, as a single shot right around the 17 to 21 day mark. I ran it at 3 grams a gallon solo. It's definitely more effective used in this manner. Although I'm not going to say it increased my yields. It did make them stretch quite a bit more. Even at 3 weeks when they're usually starting to top out. All my plants looked great, no burnt leaf tips. At more than 3 grams a gallon I noticed I would get tip burns.
Since I've begun using dizzlekush's formula I don't see any need for the Bloom Booster. Switching from the ammonium sulphate to the ammonium phosphate at week 3 will give you the extra P that would otherwise come from the bloom booster.
This is strictly based on my experience using Jack's. I'm sure there are others who are more knowledgeable and can go into greater detail, especially regarding coco.
I hope this is of some use.
Glad to see you're liking the formula. Do you see any differences compared to running the 3-2-1 formula? I'd imagine yield would increase a bit since you increase CalcNit application by ~25%, but maybe not. Also feel free to be overly critical in any constructive criticism you might have about the formula. I like to hear others experiences with the formula.I'd go with Jack's Hydro along with the Calcium nitrate. They offer a package price for both.

Amazon, Ebay and Customhydronutes.com. Whichevers got the best price. CHN is gonna be the best choice for the Potassium Silicateive been using 3/2/1 for some time now and have never had so little problems with my plants. Super Healthy from clone to chop. No pest, def, toxicity, leaf curl nothing. Just super healty plants. If this fromula will increase yeild a bit iim gonnna try it. Where did you source your other stuff from?

There's more Mg than P in Jacks, and Jacks Professional has extra Epsom compared to Peters Hydrosol which otherwise is the same product. Jacks does not need additional Mg.I'm also curious about the no-epsoms. I see the S is taken care of by the (NH4)2SO4 but isn't Mg going to be lacking? Are you running this with RO water or tap?
Compatible yes, benefit no. Only reason I see to do it is if trying to limit NO3 levels while maintaining high Ca levels, which would be to satisfy some pseudo-scientific notion about Brix, or plant defenses, or senescence, etc. No real legitimate reason not to get all Ca levels from CalciNit if using solutes, the plants N requirements are always greater than its Ca requirements.Do you think this formula would also be compatible with (or benefit from) some CaCl2?
Its a side effect of boosting phosphorous while keeping NH4 in check. The S being essential for flavor is a popular notion that AFAIK originated from that fact that certain crops like Brassica family and Allium genus vegetables (mustard and garlic families essentially) have huge S requirements for the production of the crops essential oils and organosulfurs that make up the main constituents of those particular crops flavors. Someone decided that that may have some relevance to cannabis and boom, the S = flavor notion was born. It almost makes sense since S is required in large amounts to create terpenes and terpenoids (Mevalonate and Non-mevalonate pathways), but then again N and P are required in even greater amounts for terpene/terpenoid synthesis, and you don't see anyone preaching N for flavor.Also, I understand that sulfur plays an important role in flavor - and always thought there was good reason to use it later into flower - hence boosting epsoms at the end. Here we're pulling back on sulfur. Is this by design or a side effect of boosting phosphorus while keeping its attached cation, ammonium, at the same level?
I will say i do like jacks its fairly simple but i have noticed that my yeilds have suffered greatly.
I have ran the jacks pro cal/nit and epsom. Also ran the the jacks hydroFEed and didnt really notice much of a difference between the 2 grows. I used hammerhead and MOAB in flower but like i said yeilds were less than par but the plants were VERY healthy. Any input on a different approach im all ears.
How did you manage to get really healthy plants, but lower yields? The two travel in lockstep for me...
