Questions about Epsom Salts.

[Eugenios]

Hello boys and girls. Happy Sunday. I have some questions regarding Epsom Salts. I have a dry product called Green Leaf which contains 16%MgO and and 32% SO3. It says it is similar to epsom salts. It suggests to be used once a month to prevent mag deficiency or every 10 days to treat mag deficiency [1tbsp(15gr) per liter of water]. I'm growing some autos in BioBizz Light Mix. I have never used epsom salts before but had mag def in the past. Do you agree with the suggested use of this product? I was thinking of using it in 1/3 strength(5gr) every watering or every other watering. Any ideas? I've heard that So3 is super beneficial during flowering. Thank you and God Bless. Happy Growing!

P.s: I won't upload a picture of the product because it's not in english.

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!

Amazing reply! Thanks for all the precious info my friend! May you harvest huge yields.

Wise words piratebug Epsom salts are a mega important secondary
I use them as a foliar spray twice in veg regardless

Should I add e.s. before base nutrients or after? So far I first add Silica, then CalMag(4%calcium, 1%Mg), then Base nutrients and then diluted pH down if necessary.

What if the mag def is bad? Should you increase the dosage? Or continue to feed the 3/4 tbs per gallon until it goes away?

Green Leaf which contains 16%MgO and and 32% SO3. It says it is similar to epsom salts.

FYI, this is exactly epsom salt i.e. MgSO4. They also left off the 7H2O molecules which makes up the rest of the percentages. I couldn't find anything on the Green Leaf product specifically but you can just buy the standard grocery store epsom (unscented). I recently picked up a four pound bag at Kroger for like a dollar a pound or less.

how much do you add have you heard of making SWEET i tsp of cane sugar 9 table spoon of epsom diluted into a gal of distilled water then using 15 ml of the mix into your waterings i just started on it 3 weeks ago my buds are liking it a lot

Green Leaf is just the translation I gave ylfor you guys.

This is the product below. Greek letters but you can see percentages of each mineral

A low pH will limit mag uptake such that if I know I am providing magnesium and I see a def, I would raise pH before trying to add more mag.

Would allowing the soil to dry out more between waterings help? Or would that make the ph lower and cause more issues?

Another couple factors are cold/wet soil.

Funny you bring that up I’m on my basement floor

 

[Renfro]

With soil you should already be allowing the soil to dry out. Failure to do that will likely cause root rot.

What’s your opinion on temp? Could being on the cold floor be causing issues?

no, that would be more likely to limit P uptake

Bro do a soil test to find out if your soil is Mg deficient. If you have plenty and you add more you risk other issues. Manage Mg deficiency with foliar application.

its a light mix so it's bottle fed.

You can sprinkle the top of your soil with the Epsom salts and water it in with your regular nutrient mix.
