CALMAG IS NOT A THING

You have many newer growers that don't understand the different nutrients. Many don't know that calmag is calcium and magnesium.

I agree that it is an industry thing. Specifically the cannabis nutrient industry. It's a product targeted towards cannabis growers and is highly profitable. When you can mix a few pennies worth of ingredients with water, put it in a liter bottle, and sell it for $20 the profit percentage is in the thousands.

I've never once used calmag in decades of growing. That includes soil, hydro, coco, peat, etc... I don't get calcium or magnesium deficiencies because I feed the plants what they need. And not with a dozen bottles either. Just a simple inexpensive nutrient that contains what the plant needs. There are many of them out there.

I always get a chuckle when I see growers paying expensive prices for fancy nutrients that don't contain enough Ca or Mg and are using calmag. The marketing geniuses behind many of the overpriced nutrients could sell cat piss as lemonade and have people lined up around the block waiting to get a drink. And they'd come back for more.
