6%? I didn't see that coming.
1g in 10L would be 6ppm, so in 4L (1usg) is about 15, and you are putting 3 in.. about 45ppm Mg
45ppm Mg should be fine in just about any media. Past 60 is getting a bit sketchy, and 80 is where some plants start dropping yield.
Lets just look at that 1 (of the 321)
It's about 10% Mg isn't it? (it's been a while) So again, 1g in 10L=10ppm. Makes 1g in 4L about 25ppm more. Plus the sulphur. 16% right? Maybe 40ppm of that.
Looking at a table another growers posted (on another site) the 3 of jacks gives 51 and the ES 26, making 77ppm Mg. IIRC it's 3.8L in a G, so they are probably on the money.
It is high, and I can see how some might leave the ES out, or half dose it. Or need more Ca than the 100ppm, in soft/ro water situations
