    Is cal mag truly organic I stopped using it and and tried to add it more in my mix with amendments but I'm still seeing slight cal mag issues! I'm worried the cal mag I add to my waterings might hurt all my precious microbes I work so hard to breed!

    They make organic cal mag, made with with calcium carbonate and magnesium nitrate.

    I was wondering about that,
    The chelates? However you say it
    Is this a problem with the organic cal mag? As far as microbes.

    I get that we routinely add microbes
    So in my mind it would be acceptable.

    The rev goes on and on about that and the acids but then says he has a bottle of calmag, unless I just didn't understand correctly.

    Maybe this is one of those contradictions richarddrysift was talking about.

    But yeah, I cant imagine not having some fast acting calmag at hand

    I have no idea haha but I needed it specially under led which requires more calmag. I think I'll just start adding more calcium inputs into my soil and start using more epsom salt for mag to get around it.

    I have often wondered this too, and I think yeah adding more sources of cal/mag to the soil to be broken down by the microbes I think would be the best way to go. How can we achieve the right concentrations in the soils?

    As far as organic calcium goes, I think bat and seabird guano are naturally chelated and should be readily available to the plant.
    One of the more knowledgeable people in the organic forums said that bone and crab shell nutrients become available at different rates, so I use both in my mixes.

    Is there an organic calcium folier?
    Boiled eggshells or something?
    Do any of you spray epsom salts?

    Get General Organics liquid calmag it's the only one I know of that is OMRI listed safe for living soil. It's recommended by the rev. I've been using it for years now. Add it at 6-10 drops per gallon of water; dosing by what the label says can cause salt buildup but using a dropper you can add it at almost every watering if you need to; only needed when using RO or distilled (dehuey) water though. Rainwater has all the macros already. I also add crushed eggshell to my worm bin and mineral inputs to the soil directly but it's actually kind of hard to provide macros like cal & mag in soluble form if it's not in the water. Here's a link:

    I have a question because this whole conversation is puzzling. Doesn't anyone use dolomite lime in their mixes?

    I use no liquid cal/mag and never have, but have not had a cal/mag issue in over 8 years. I did 9 years ago after listening to Coot and some bad information on dolomite that had no relevance to container mixes.

    I DO add a bit of Epsom Salts to fresh mixes because the Mg in dolomite is slower to release than the Ca. Once it does start to release, the Mg becomes a non issue for several years at least.

    I use the dolo just for pH buffering and use other sources for more Ca, but the dolo seems to provide enough Mg on it's own. I know I don't need to add Mg specificly.

    Am I missing something here?

    Not missing anything
    I have just become so used to adding calmag via bottle to my indoor grow

    Now That im moving towards fully organic water only I just want to make sure I have my bases covered in case I mess up and find myself needing to add. Im still learning and between fungi, nutrients, microbes etc
    My head is spinning. Lol

    But Im doing the research in advance.

    Outdoor im currently running dry amendments, n tea
    But i want to mix it all myself instead of buying it next year

    I do also add egg shells to my worm bin and bananas alot! Lol but I use my sink water it's well water and I bubble it for 24ish hours! To be honest I don't know if I have good water or not but I've been using it for about 2 years! I will get a small bottle of this cal mag and use it every once in a while just for a small boost of cal mag!

    I add a handful or 2 of D-lime and garden gypsum when I recycle the soil. I ran out of calmag last year and stopped using it for awhile but after a few weeks some of the older fans were spotted. Went back to giving calmag again and the plants are now happy & green. I think it has a lot to do with your water source. Dehumidifier water is what I use mainly because I collect a lot of it but it's very low ppm. When I give rain or spring water I add nothing at all.

    If you have been getting along without it you may not even need it. Well water should contain macros already.
