Questions about Epsom Salts.

[Dapper_Dillinger]

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?

Yes epsom fully dissolved when shaken. If your using tap water check your ppm you can add up to about teaspoon of Epsom salt. I use 1/2teaspoon Epsom salt and 3ml call mag in distilled water 250ish ppm water/feed/water. Most cal mag is 3parts cal to 1 part mag. Check ppm if you can

Depends on what you are growing in. I hardly ever hear of calcium deficiencies from soil growers but often from coco growers.

I'm now using Jack's 3-2-1 without any CalMag supplements and I haven't seen any deficiencies, even in coco. My tap water is 38ppm too.

Thats awesome quality water for tap! 3 21 is 1 gram or 1 teaspoon of Epsom, correct?

1.1 grams of Epsom salts

I use a pinch in every watering until flush. Topdress it too at times, dont have many issues with deficiencies. Plants arent complaining! Use 2 grams per gal. pot size. 25 gal. is 50 grams of epsom salt. Greens them up nice for outdoor grow.

I stand corrected

I wouldn't take advice from anyone suggesting to top dress epsom salts.

For the past year, every time I read "epsom salt" I think "Epstein salt."

I was gonna say i would be worried about salts contacting bare roots and causing burns but ive only grown a few plants successfully, so im just stating what works for me

Im more confused now @MICHI-CAN Can you summerize the message you are trying to relay with this article?

Epsoms salt is best used as a foliar. Not a salt building soil feed.

So I shouldn't mix it in with my nutrients?

I don't and have better results here as foliar. All I am saying is look into the science. Almost a century of research available if you get past the click bait and read instead of watching.

Honest best wishes.

Whats your ratio for foliar spray epsoms

Whats your ratio for foliar spray epsoms

1/4 tsp in a quart. Always with 1 Tsp fish emulsion. Miracle band aid. Discard after 2 days if adding fish. Turns rancid. Plants still like it. You won't.

It sounds like you're growing hydro. Add it to the nutrients if you need more Mg and S.

Listen to Renfro's advice on that last page.

He's not using soil.

I heard the undersides of the leaves should be sprayed at lights out, is that right? Just a light mist or a heavy spray?
