New Grower Yet another thread concerning cal mag

[Coffee Monster]

I've been using Botanicare cal mag and was startled to note it was 2-0-0 npk.

I suddenly connected this to some N tox symptoms I've had.

I see where a lot of the other companies cal mags have N as well.

I know I've seen some recommendations for cal mags without N, but cannot seem to locate the appropriate threads.

I'm lookin at GH GO cal mag as a possibility, I would prefer somethin I can get through Amazon. What would you reccomend guys?

Hey mate when i start my next grow im going to order from the canna mono range they do calcium and magnessium in separate bottles.
Bit more work having separate bottles but cal and mag defs dont always come together

Thanks sanguine. I did notice a seperate set on Amazon but they weren't Canna. There is certainly logic to your approach, I might go this direction. I've had a bad Mag def but not Calcium so i see where you're comin from. I've got epsom though so I think I'd still like a combo product but perhaps at a reduced dose which I could then supplement with epsoms as needed. But no extra N!

Having a quick search on google.
Earth juice oily cann is 0-0-0
Finding it near impossible to find other N free suppliments
Theres a couple of 1-0-0 like
Gh calimagic
Supernatural green stay

So far the best options then are either General Organics 0-0-0 or General Hydroponics at 1-0-0
Or a one part or other source of Ca plus Epsoms

Now I read GH doesn't always use the best ingredients and that the carbonate forms are harder for the plant to take in

Looks like I'm sticking with Botanicare and epsoms until I can find a better ca

Thats true dude but if the add chelates or humic/fulvic acids this helps absorbsion to the root zone but that takes time to have effect i think.
The most common source is calcium nitrate which is easier absorbed by plants but is 15%N thats why nearly all suppliments have high N values!
Im off to do some more reasearch

So, I still use Botanicare's calmag. But when I get a finicky one, I skip it for her and use this instead, just for that one plant...
