Jacks 321 Nutrients

Hey guys so i’m using Jacks 321 nutrient feed & im a little confused . On amazon the description says to do 3g Hydro , 1g Epsom Salt , 2g Calcium Nitrate , but that doesnt really make sense to me cause it’s called “jacks 321” & it’s going 3,1,2 . I hear people do 3g Hydro , 2g Cal Nitrate & then 1g Epsom Salt . How should i use this stuff ?

The description is correct. You mix in this order because magnesium doesn’t mix with the cal-nit.

Kootmeds JACKS 321 feeding schedule.

I use this feeding schedule for JACKS 321 but with PowerSI. Its basically the same feeding schedule for Jacks, it's just easier to read.

I use Masterblend 4-18-38, epsom salt, and calcium nitrate. It's very similar to Jacks. My journal is in my signature with lots of pictures. I'm growing in coco coir under a TS1000 LED. I run a slightly lighter than they say to use mix of 2g masterblend, 1g epsom, 2g calcium nitrate. I run this on many kinds of plants from seed onwards.

It's 3g of Hydro, 2g CalNit, 1g Epsom, but always mix your reservoir with the CalNit LAST. I dissolve my Hydro and Epsom together in a small bucket, add to rez, then dissolve the CalNit and add it last.

321 is the ratio. The full feed schedule is 3.6g of Hydro 2.4g of calNit and 1.2g of epsom salt.
