Cal-Mag Myself?

[Rozgreenburn]

I just mixed my first try at a homemade organic Cal-Mag solution. Powdered eggshells and clean Epsom salt. When I get the ratio down, I'll post it.
Starting out at 1 TBSP eggshell, 1 TSP Epsom salt, and 1 Qt water. I'll use 1/2 Oz in a gallon of water each watering.

I was concerned for a minute, thought you were Cal-Magging yourself lol. I hope you get it down, sounds great....

I've been doing the pan fired egg shell, with some vinegar 5% acidic, a carboy, poked into a mason jar lid, so more like a calcium acetate.
My understanding, the vinegar, leeches the calcium from the egg shell, the pan frying is remove all the variuos membrane from the shell.
I like the idea of adding some Epsom to mine.
Now I'm on a yeast for soil biology trail. Always something to learn!!

i use from seabird guano to crabmeal and many things that have calcium and other micro /traces in it. Organic is great to overdo it like that, but for as boost and guratee of semi fast release I use my diy elemental recipe. Works great both drenched and topmdressed

Dolomite Lime / Garden Lime

Dolomite Lime enriches soil with calcium and magnesium while helping to regulate and raise pH levels. It also helps prevent and cure blossom end rot in tomatoes and peppers. Simply mix at a rate of 1-2 tablespoons (max rate) per gallon of soil and mix into the top 2-3 inches of soil. This is...

u can get this brand on here for cheaper than Amazon, but they- do sell 5-20lb versions on Amazon (just a lil more costly)

I choose this cause it’s powder, it’s same ingridents as elemental but no fish protein and way cheaper. I apply 1/4 cup every 2-4 weeks top dress for every 25 gal soil/medium and tea it at 1/2-1 cup every 50 gallons of water . bonus is no nitrogen and very soluable and works great. I tried this last 2 years in flower as my cal/mag addition vs elemental ( cost) , only thing it lacks is gypsum and that’s also cheap but I don’t seem to need it?

Amazon.com

point is version I’m using is 100% powder and easy to use like elemental but way cheaper , very similiar %’s
look at ingredients
Elemental = Calcitic Lime, Dolomitic Lime, Gypsum and Fish Protein Hydrolysate vs Dolomitic / Calcitic Lime (cheap “diy version “)

no arguments to ur method it’s just egg shells take a lil bit to break down, I put ‘em in my compost/worm bin , nothing wrong with s-ringing em in too it’s just the release time I wouldn’t trust exp if it’s not real soil/outdoors without a extra boost. The great bonus to organics and adding stuff it’s hard to overdo it vs non organics ( not everything but u get what I mean )
