Specified. Also thats what biobizz say for their line....
Are you asking me for specific brands?

Roots organics has an organic bottled Cal-Mag. TPS nutrients does as well. Bloom city has a 90% organic Cal-Mag that they claim won't hurt microbial activity in the soil.

Maybe try out the floraflex wicking tops for the fabric pots they will make watering more even and help keep a little more moisture in the pots. Also be sure you dont have the pot right next to a fan or intake

Sure but... cant be sure of much these days.

At the end of the day its all organics.. its all EARTH material:peace: spewed from a volcano or dug up and then... enhanced maybe? This enhancement im talking about... that extra process.

If you water with bottled calmag in your organic soil you re killing the microbes consistently. Choose an organic.

Then 1gal pot is too small. Ive had organic grows with 3.5 gals. Minimum id say to have a decent 4 weeks of veg before switching to flower.
Could u elaborate? How does calmag kill microbes?

Truth is i got no scientific back up. Just my observative nature. Meaning i ve used a couple of em when i started out and it just didnt flow right.
Kinda like do i need a 4k or a 6.5k for veg...

Do you speak fluent microbe? Whats your take on this

Well the only part of my feed which isn’t organic is the calmag.

Companies also state that their product doesn’t harm microbial life. Leading me to think some do..

I dabble.

Im not into the shitalk thing, this is just my exp.
Are you using it regularly? I can get my hands on a proper microscope maybe i could do a little experiment. Been thinking bout this for a few weeks. Not for the calmag thing but i could definitely try just a tiny splash of water with calmag and check the microbes real time. Hmmmmmmmmmmm

Unless the product specifically states it won't harm microbes, it likely does.

In my experience, most people don't actually need CalMag, they just have a lockout of some sort and CalMag almost always makes their issues worse. Excess potassium and calcium can lock out Mg, as can poor pH of course.

One can foliar feed with Epsom Salts for Mg until the pH/nutrient issues are corrected.

Langbeinite can be good stuff, but under two conditions: 1) You are 100% certain K isn't the cause of your lockout, and 2) It is used in small doses.


Ca, Mg, and K are very much intertwined with one another. If one is in excess, the others will be locked out. This is especially true with Calcium, as "Most of us have enough or too much calcium in the soil for plants to use just as a nutrient. The more calcium in your soil, the higher the pH of your soil can become."

Here's some more information on the relationships between Ca, Mg, and K in the form of pdf files for anyone interested.

and an article on calcium from NOFA, which has loads of valuable information.
