What Deficiency is This

There's no such thing as cal mag def, only calcium deficiency and magnesium deficiency.

Epsom salts is magnesium sulfate and thus won't do anything about calcium deficiency, just magnesium and sulfate deficiency.

Well. No. Cal/Mag go hand in hand for various reasons. And for various reasons, the ganja grown indoors, is susceptible to the lack. It is easy to see why if we look at the pH charts, but that is not the only reason.

So, unless you are peicing it together with epsom salt, the rest of us buy it together. Since I can predict now when I see this, I have Cal/Mag is a bottle.

That is why it is the cal/mag deficiency. They do look different and the are different. But they show up, often at the same time. One is around the corner from the other, etc.

So, just treat for both.
