Epsom Salt for organic soil

[Trickcomanche]

I'm wanting to add some Epsom Salt to my water to help fix or stop these purple stems. I'm just not sure at what concentrate or PPM would be best to add to the water for these plants. I'm early week 6 of flower.

1 gram of Epsom salt in 1 gallon of water should give you around 26 ppm Mg and 34 ppm Sulfur.

I'm currently feeding around 75 ppm Mg and 100 ppm Sulfur... and still getting some red/purple striping on older growth.

I think I remember hempy saying something about red on the stem around the nodes being a Haze trait but i'm not 100%

So 1 gram is 60 ppm total..? Is that the dosage I should use ?

 

[zagros_s]

1 gram has an ec of 0.237... you'd have to convert that to ppm.

As to how much you should use.. no idea.

You can go hard @ 3 grams/gal or light @ 1 gram/gal. It's really depends on how much is already present in your media/water.

Ok, thanks for the info.
