Exactly, needs to tailor it to his base soil.
Bone meal contains extra phosphorous, gypsum has sulfur, & shells take forever to break down.

Bentonite clay also.

I saved a thread by @speedwell68 and am wondering about trying it, calcium chloride. If I try it, I'll dissolve very little in the nutes rather than their approach of a one-time soil treatment.
I'm having some beneficial results with soluble gypsum, but am still unsure about the optimum amount. It appears I need to use more than I am (0.69 g/gal), but dissolved in my nutes and poured through substrate it raises leachate pH beyond my desired target.
Your question also reminded me of this news item (emphasis added):

That leads to terra preta, a dark rather than light soil.

What nutrients are you using?

calmag+ xanthan gum produces a calcium chloride hydrogel. I use this outside in my sandy acidic loam, with some 10-10-10 and a pile of leaves.
Applied to compost leaf, NPK nutes or biochar, it makes a time release fertilizer, holds water in the soil and releases it slowly.
Xanthan or guar gum polysacharrides have to be pre mixed with iron or calcium, or it will strip it out of the soil.

Polysaccharides as safer release systems for agrochemicals - Agronomy for Sustainable Development
Agrochemicals are used to improve the production of crops. Conventional formulations of agrochemicals can contaminate the environment, in particular in the case of intensive cropping. Hence, there is a need for controlled-release formulations of agrochemicals such as polysaccharides to reduce...

Dang, I just looked up the label and there is indeed no calcium listed on it. Weird. I know in the normal 321 formula, the "2" is calcium nitrate, and the base nutes have pretty low N. Not sure I would use calcium nitrate if the base is already 18% N tho...
You could always call or email JR Peters and ask what they recommend...
I am waiting for a reply now. They specifically said not to use the part b or there 2nd part to supplement for calcium in the outdoor version. I am wondering if my source water will have enough calcium. Planning to use normal tap water.

That's kind of shocking, but depends on your water source, I guess.
Good info to know about the 321 Outdoor.
Not sure if this is a joke but this version is all in one.

Not a joke but didn’t you say it doesn’t have calcium? Its jacks why not just use one that does.
