I’m looking into getting away from bottles and saw this kit. It contains the master blend dry fert with calcium nitrate and Epsom salt. My question would be to use this in flower would you cut out or down on the calcium nitrate and feed the mb with the Epsom salt? The Epsom salt is very overpriced through them and I have a giant bag already so I won’t be buying theirs. Just wondering if anyone has any experience with this or anything like it, sure seem cheating than paying for water.
Has anyone used the master blend kit

Sounds like the Jack’s 321 mix using jacks calcium nitrate and epsom salt in that ratio 3:2:1. I’m going to look at the nutrient just to see what it’s all about.
Sweet, the numbers on all of it look good but not real sure how I should use it in flower. I found some info saying to use all three but seems like the nitrogen would be real high.
Looks like they push the p and k harder then jacks and drop the nitrogen slightly in comparison.

Thanks for the info, I saw basically the same measurements for the MB but I did find a guys suggestion to cut back on the calcium nitrate after the stretch. I’m gonna go for it and see what I can do with it. Sure seems like a better deal than paying for water.
Master blend is just another Jack’s 321 just stick with the 2 grams of cal-Nit and 1 gram of Epsom and what ever base your using for the p and k
