I'm running 6/9 in coco with a
dosatron set-up. What I need is a magnesium concentrate to bring my ppm's up 20 ppm's more. I would like it to be 5 - 8 mls per gallon, if possible. How many grams of epsom salt per gallon are needed to achieve this? Cutting Edge Solutions Mag Amp cost $80/gallon, so I'm looking for something similar at less cost, that I can make myself.
Thanks.
That company is one of the worst values out there. Mag amped my ass. Good of you to ask about this, JPlord. I also did a 3k mpb like yours in my walk-in closet. Thanks for that.
So if you need 20 ppms more magnesium, you will need a 4-6 pound bag of epsom from the drugstore, and your digital scale. I like putting the salts into a freezer bag for a containment vessel in between steps.
One gram of salt per liter is 1000 ppms. Of 1000 ppms of epsom, 9.8% of them will be magnesium. 13% will be sulfur. Sulfur is good, I'm sure you've heard. So lets say we will get 19.6 ppms to make this easy. That would be .2 grams per liter. Which is .757 grams per gallon. So .75 grams per gallon would give us about 19.4 ppms magnesium.
You should check out the fertilizer salt threads. We can maybe save you up to thousands of dollars a year. If you post your nutrients, we may be able to help you reverse engineer it for super hella cheap.
Good to see you around here.
Edit-I reread, saw the 6/9, is that lucas? What are the NPK values for 6/9 lucas again?
