Jacks 3-2-1 vs 3-2 -- Extra Mag or Not... - Nutrients and Fertilizers - International Cannagraphic Magazine Forums

plumsmooth · 01-18-2018, 02:09 AM

Over the last few years researching, I have seen both sides...
Jacks has plenty (mag). vs
This or that strain needs more or Jacks needs more for Cannabis...
Not sure how the 1 of the 3-2-1 Mag came to be.
Sure there is a worthy history...
Even Jacks/Peters mentions adding extra Mag so that might be the origin...

I wonder if any of this has to do with the potential dissolubility of Magnesium in harder waters mixing jacks.

Pre-mixing I have always even in Distilled water noticed a final precipitate left at the bottom?

Any feedback would be really appreciated...

Thanks for your time...

I got Caught with my Own Poll.
I had to make a decision and I chose #3 because I haven't tried it both ways enough to be sure. Sorry.

I guess I need to do a side-by-side: Funny thing is my current strain c99 has been considered my someone somewhere a Mag hog?

Jacks 3-2-1 give you

n 119
p 42
k 171
mg 76
ca 95

That's too much, I've had issues with less Mg than that.

Jacks 3-2-0
n 119
p 42
k 171
Mg 50
Ca 95

^that's about perfect. Mg should be roughly 1/2 of Ca, and Ca should be 1/2 to 2/3 of K

if you see magnesium deficiency, then add magnesium
