yep me too. the state can come check me on that....wherever I can find them (MUST be organic, I've become annoyingly anal about that),
What if that's what you want?Kelp Meal
Personally, I love kelp meal...stuff is loaded with everything, including Calcium (1.904%) and Magnesium (0.213%). My concern with epsom salts is that I've read that, like any salts, it will liquidate the soil's microlife.
I can see new growers everywhere pouring a half bag of Epsom salts in their feed water to “correct” the lime green color of new growth!epsom salts is magnesium sulphate, not magnesium and calcium.
the Cal-mag supplements are really way over priced IMO.
You can easily use Dolomite lime which is essentially calcium and magnesium, but you'll need to use the finest grade available. It breaks down relatively slowly and is not immediately available to the plants. Works excellent for gaden beds, but not as well for containergardening for short lived plants.
For immediate correction of a magnesium defieciency, use Epsom salts
"Magnesium sulfate is a chemical compound containing magnesium and sulfate, with the formula MgSO4. In its hydrated form the pH is 6.0 (5.5 to 7.0). It is often encountered as the heptahydrate, MgSO4·7H2O, commonly called Epsom salt."
For immediate correction of (the more rare) calcium deficiency use calcium peroxide.
Most chemical fertilizers supply ample Mg and Ca, although some companies sell a Cal-Mag solution separately to extract more money out of your pockets.
The vast majority of Mg deficiencies you seen on these forums is due to too low of a pH, which causes the Mg to be locked out and thus unavailable to the plant, resulting in a deficiency
Cannabis does however require a vast amount of Mg compared to other plants, so it's not a bad idea to add some epsom salts to your water every now and then.. especially if your leaves start to grow thin and ridged with a lime green colour as opposed to a darker shade.
