I'm not sure exactly how you mix your soil but here is how I do it.Carbon is like a different language to me talking soil. I see the word but what does it mean. On a quick net search I got a clue maybe. Do you mean coco coir and all the roots I till back in over and over? Yes to them. Can you give me a simple definition of carbon for this application?
Well, now that we see all the goodies in it, if I'm seeing mag def there's something off. Yes?
The soil in the Cherries DubeLee SIP is the tested soil. It grew pretty well with a slight need for mag look on leaves in veg. I gave 3 ml cal/mag 3 times, maybe 4 and she's calmed her need for it now she's in flower so far. That. I don't think this soil has to grow with def's normally.
I'm thinking it did well for growing all the pot it has and just needs a little love. I've been amending it by the book for years, which is a blessing and a curse because I didn't have to learn anything but to add some mag. I'm about to learn something I hope, and finally fix this soil! Thanks for your input!
I mix used soil with coco 50/50 and all my ammendments, basically Rev's list. I run that thru my worm farm. Thats my EWC Supersoil.
Then I mix that supersoil into a potting mix.
I do that by using equal parts of EWC Supersoil, coco (because a ton of the carbon I added in the ewc process got eaten) perlite( to fluff the coco) and used soil, as its balanced and innoculated with life.
Thats the mix you should be getting tested. Or whatever your final potting mix is.
Your cec section shows borderline minimum magnesium and thats because the CEC is slightly heavy in calcium. When you hear people talk about Cal to Mag ratios, CEC is where those ratios come from. Thats the ratio of cations prepared onto colloids awaiting consumption.
Any blank spots on the platters are filled by hydrogen.
If you could lower your calcium 6 or 7 points and add those points to magnesium you would have perfect basics.
Calcium will drop on its own if you water to runoff, as calcium is very electrical but not very sticky for how heavy it is, which will sway the ratio in magnesiums favor.
Your soil looks very good. If you are adding a calcium like gypsum or calcium carbonate, maybe just lower it by a small amount. That will allow a few more magnesium cations onto the platters (colloids).
Look how high all your minerals are, used soil is still really good stuff, its just missing carbon and organic matter. It has tons of fungii in it too for all that Phosphorus you have.
