0% N Calmag?

32 posts in this topic

Posted (edited)

As the title suggests, is there a calmag that is 0% nitrogen? Please leave any N numbers and cal to mg ratios for your calmag and its make. Its very hard to identify which brand has what so maybe a list here will help not just me but others

i use mag-cal by intense atm, it's

 

2.9% N

5.0% CaO

2.5% Mg

 

my water is very soft, the water company says "moderately" but i have only really been getting serious issues with the last couple of grows, so not sure if it has softened further from before, but i am now looking at using at full strength as 1ml isn't enough to stop cal def :wallbash:

I think GHE do a fairly natural cal mag that has minimal amounts of N. Can't find more stats on it though upon a quick look

Ionic CalMag Pro is 3.8% N; 5.6% Ca; 4.01%Mg; 0.15% Fe. Calcium nitrate is a standard calmag source so might be hard to find a nitrate free one. You could make your own up with Solufeed's products which have  the single minerals available  in powdered chelated EDTA form. You'd want calcium, magnesium and iron chelates.

Edit: The standard magnesium compound in most/all calmags is a nitrate as well. With both compounds being nitrates means they don't react in storage.

Cheers for posting that, I spoke to the chemist at TNC and he said when he has more space he's going to do a 0% N Calmag. It's that conversation that got me looking. 

 

I'm OK with some N in it but I'd like to find <2% ideally and with a 3.5 : 1 ca : mg ratio

They seem a technically-adept company. I use their Mycorr and Bactorr range. For 2-0-0 NPK ratios look at Botanicare CalMag Plus and Growmore N-Cal-Mg. They're the lowest I can find.

yes mate, it only says calcium and magnesium supplement on the bottle, so i assume no other additives.
