Questions about Epsom Salts.

Although magnesium cations and sulfate anions are considered secondary type nutrients / minerals, those two minerals are the cause for more plant type nutrient deficiency than most people realize. Like the bones found in every living mammal, nearly 55% of a plants metabolic structure is made from magnesium cations reactions, and sulfate anions are also very important because that mineral is greatly responsible for allowing a plant to uptake all the other nutrients it needs to grow. So Epsom Salt / Magnesium Sulfate should always be included in your growing strategies. But don't ever rely on ca/mg supplements to solve a direct magnesium deficiency because all of them contain 3 parts calcium to 1 part magnesium, which most times won't fix a magnesium deficiency because an overabundance of calcium will lockout a plants a ability to uptake magnesium. So if you have a magnesium deficiency, use only Epsom salt @ 3/4 tsp per gallon, or if you want to add a calcium supplement, use a ca/mg supplement but also add Epsom salt to the mix @ 1/2 tsp per a 3ml ca/mg supplement so the ratio is 3/2, to avoid a magnesium lockouts! And for prevention measures, if you add a 3ml ca/mg supplement and 1/2 tsp of Epsom Salt to every 1 gallon of water or feed from day one till 2 weeks before chop, you won't ever have to deal with a calcium, magnesium, or sulfur deficiency!
This honestly just clarified everything i wondered about calmag and Epsom salt. Thank you for sharing your knowledge with others. I hope its ok for me to copy and paste this in my grow journal for further reference

What do you recommend for levels in coco?
See how that works and up it if need be, maybe 1.5 ish, if you get up as far as 2 then I suspect pH is the real issue. Just make sure pH isn't the limiting factor first. Whenever I know I am supplying magnesium and I see a magnesium deficiency then I look at pH. A pH number just a few points too low can cause a magnesium deficiency.

So the chance of having a Cal deficiency using tap water is pretty low? Is this true? If currently I feed>water>feed>water could I replace the regular Ph'd water with a Epsom salt water treatment at 3/4 tsp per gallon to keep Mag levels in check? Does Epsom salt fully disolve when shaken?

my tap is around 150ppm and my plants get CalMag deficiencys if Im not adding it.
