Oh, I didn't mean to use that alone. Not sure if that's what was understood, but what I meant is to mix the food, without calmag, add that mixture to the plant having nitrogen issues, and then add a tiny bit of the RAW product to that plant only.Coffee'-- GH CaliMagic/GO CaMg+ ("organic") are 1-0-0, and 0-0-0 respectively; CaMg+ is all carbonate based in a fermented sugar base (my fav'), while the other is their fully synthetic formula using nitrate in part... the Botanicare is great stuff, but also has lots of other goodies in there, including amino acids which I believe will figure in the total N content %,... it's not bad for N really, compared to AN's (4-0-0) version and especially that RAW product-
-- funny, I was just helping somebody in Sick Bay when this product came up,... true it's used in relatively tiny amounts, and usually isn't an issue,... but N sources do add up, and worse, N is one of those nutrients that is taken up whether the plant needs it or not; what doesn't get used, is stored in other forms, but there's a limit to that before toxicity issue start manifesting,... How are you growing? The CaMg+ may not be the best choice for hydro, that's what the Calimagic is about though it can be used in any grow style... Sanguine has suggested good alternatives too!

As for the relative availability of Ca-nitrate vs. -carbonate, I'm not buying there's a significant difference:
--the entire molecule isn't absorbed, the process just doesn't work that way...
--this is an aqueous solution, in other words these ionic compounds are dissolved and separated into their component +/- ions, and it's in these forms that they get absorbed,... well, all except carbonate, which in water under typical conditions for growers, becomes (instantly basically) bicarbonate (HCO3-), not absorbed by plants,.. but this bicarb-carbonate part of the molecule is what involved with pH buffering in solution... (that's a whole separate lecture right there!)... sometimes this carbonate is helpful, but in hydro, with lower pH range demands, it's not, hence the alternate formulations,...
-- be careful mixing epsoms with dedicated Ca-Mg products,... the Ca and SO4 from the epsoms can cross react if in sufficient concentrations and form gypsum as a flocculant precipitant...
>>>about ammonium uptake, that's incorrect; it too will get absorbed just like nitrate does, and is actually more likely to trigger toxicity issues because of how it's metabolized and stored,... one reason why most canna' fert's use a high nitrate:ammonium ratio,... and the RAW does not have ammonium in it; besides, ammonium is cation, n/a for this purpose-->
RAW CALCIUM: structure
RAW Calcium/Mag contains 15% calcium and 3% magnesium. RAW Calcium/Mag has optimized the ratio of each element in a Water soluble formulation of calcium nitrate and magnesium sulfate so that it doesn’t leave the media salty. This product is a stand alone Calcium / Mag supplement. Due to its low dilution rates a little RAW Calcium / Mag goes a long ways. Its also ideal for preventing deficiencies, treating deficiencies and for creating optimal recipe solutions. Works in conjunction with all nutrient and feeding programs.
Go back to the mixed food, add calmag and feed the rest of the gang...
