I made the numbers up as an example for the post, I don’t remember what I really gave them. As soon as I saw it was a white powder I knew I wasn’t going to like it, so my expectation was a burned plant and that’s what I got.While I love MC, I have heard many horror stories about their CalMag.
BTW, 20g/12gal = 1.7g/gal
For 5 gallons, 1.7g/gal x 5 gallons = 8.3g
However, 1.7g/gal of their Cal Mag pro added to 6g/gal of MC v1 provides:
217 ppm N !!
37 P
191 K
152 Ca
46 Mg
etc
And since you said you’re already at double the recommended dose for MC, if that means 12g/gal (!!), you gave them:
375 N (!!!!)
75 P
385 K (!!!!)
255 Ca
76 Mg
you get the idea!
There just really isn’t a good way to bring their CalMag into the mix, even with 3 of their other products!
My usual mix when I get them up to full strength is 3 Tbs (45ish mg) of MC v1 and 3-5 tsp of Botincare CalMag+ in 5 gal of 450ish PPM tap water so I’m probably pushing it very close to the edge already.
