Jacks 321

I used to have a chart for 321 and their other 1 part powders (city/well vs RO I think?) as an aside, if you ever need to chat with them, the owner's daughter (a PHD herself ) answered all the questions (issues too) with the 1 part. I had a really weird massive pH drop at about day 4 in my res. they all ended up being lawn fertilizer unfortunately.

Im hoping it's as easy as everything I read. I made sure I mixed them thoroughly and in order. I just fed everyone tonight. Gotta dust off the ole flowering green thumb. Haven't did a flower run in 3-4yrs

the part A is 5-12-26, the part B adds 15 to the N so you end up having 20-12-26
AI blurb from greengenes youtube.......
Jack's 321 is a popular, cost-effective three-part dry fertilizer recipe made by Jack's Nutrients (JR Peters). Per 1 gallon of water, the classic ratio uses 3.6 grams of Part A (Hydro 5-12-26), 2.4 grams of Part B (Calcium Nitrate 15-0-0), and 1.2 grams of Epsom salt (magnesium sulfate). [1]

I did 3g, 2g, 1g (321 has no change to the starting ph).
Maybe I need to do 3.6, 2.4, 1.2 grams /gallon.
Also, store bought Epsom is the same as ag Epsom. As long as it not scented epsom.

I do the 3g,2g, 1g forever
I have a clear container I use to scoop. It has hash marks on it for the various volumes and is really fast and repeatable.

Veg to harvest is only the 321? Loving that! I do use/will use silica. I use my weed scale and just tare a solo cup. I have seperate 1gal milk jugs to mix each salt in. Then mix into a 5gal pail.

Yup, 321 for all of it and I supplement with some Flower Girl about mid flower. I try not to exceed 450 ppm. that's the level I see leaf tips burn at.
