The pendulum of duality swings from dark to light, and back again, overcompensating at each turn, the truth is always found in the middle, the apex of the swing, the mid point, the balance, the peace.

Yeah but I grow better weed than my wife. Are we talking foucaults pendulum or the pit and the pendulum? I’m confused. Im going to drink some milk.

Milk contains too much calcium and is detrimental to proper human growth.

Totally agree, nutrient deficiency in general is greatly over diagnosed, if you’re using mainstream nutrient lines, very unlikely

From that article:
I should offer a couple of caveats before going further. I am a legacy grower turned cultivation consultant and nutrient geek. I have no formal scientific training, but I can run a well-controlled experiment and I certainly know what optimal cannabis plant development looks like. So, take this information for what it’s worth. I’m sure some academic researchers will have their issues with the informal nature of my process, but I feel confident my work is valuable to growers seeking to improve their outcomes.

The second caveat is about my physical setting. I only grow indoor cannabis, with temperature and humidity settings that never stray from the ranges of 65-85°F and 45-65 percent RH and light levels that never exceed 1,500 PPFD. For those growing in more extreme conditions, calcium uptake patterns can be affected, thus I can’t contribute confidently to the calcium conversation when crops are in outdoor or greenhouse settings.

Yeah and then look at these unhappy plants, even when all the fanleaves got stripped off still not looking vigourously or healthy.

I don’t think that high Ca will lead to these yellow toxicity symptoms, rather Mg may do that, but not Ca. Excessive Ca forms “stones” inside the leaf tissue and trichs but it’s not visible to the eye.

Then from the same author is this article on “veganic cannabis” where she writes:
" Since all soil, organic or veganic, gets more acidic over time, some kind of liming material will be applied when the pH of the runoff drops below 6.4. For this, I usually use calcium carbonate granules, top dressed on the soil surface at a rate of about a half-cup per gallon of media. One application will last three to four weeks before pH starts dropping again. Calcium is one of the few minerals that cannabis can handle in larger quantities, and the carbonate is the component that has the alkalizing effect you’ll need. This is especially critical if you are using [reverse osmosis] water, which contains no natural pH buffers."

Funny how i post about covid or misandry and my post gets deleted in seconds yet this misandry is up for days.

You know how to stop sexism and racism?
By ending identity politics, not through cultural marxism.

But yeah, cal-mag sucks. Just make your own
Plus, calcium should be low in sprouting, and gradually increase into veg and flowering.
Its not about the numbers, its about the ratio.
Thats one reason i dont like Nectar For The Gods

Surely any top range nutrient regime includes mag. and cal. in their product line. Its when we think we know best and chuck a bit extra in the balance is upset.

Hard to know what information to believe. Is calmag needed generally or not?

I use it in coco along with molasses and amend with vermiculite. I’m a firm believer in multiple sources of Cal-Mag.

The short answer is no.
Typically if you use bottled nutes they are supposed to provide everything your plants will need.
If you need to add more calcium you should add calcium, when you need more mag you should add mag.
If you keep adding mag when you don’t need it but you could use more calcium you will build up mag in your medium and that can cause compaction and other issues.
