Jacks (JR Peters) nutrients

equal parts per gallon
1.5 grams calcium nitrate
1.5 grams magnesium sulfate
1.5 grams mix 4-20-39

looks damn good to me
great bloom formula

theres enough P there if your ph adjusting with phosphoric acid

if you add 0.25 grams per gallon of mkp it looks like the lucas formula with N P:K ratios 1:1:2 which is good in the last 2 weeks of flower if you wish to leach N
the over all formula is slightly hotter but theres enough micros so you can dilute it to whatever EC

here it is with the added mpk in the last two weeks
per gallon
1.5 grams calcium nitrate
1.5 grams magnesium sulfate
1.5 grams mix
0.25 grams mpk

it looks pretty damn good and its an easy way to mix

you could mix this from memory and easily switch your mix to reduced N ratios in late bloom

fucking phenomenal

who ever made these (hydroponic special) blends knows what the fuck hes doing

here it is with PEK acid which will give you some good ph down
m guessing thatll drop your ph from 7.0 to 5.7

here is the PEK acid product

strange never noticed...my guy also is carrying the hydropinc special mix

keep in mind I run my nutes light compared to you guys

so you would end up mixing the same ratios but with less water


by far better than any other dry mix ive seen (both the 5-11-26 and this one)
theyre actually better than almost all of the high dollar brands

so here is the veg formula using magnesium nitrate

it requires ph adjustment with sulfuric acid (battery acid) to raise the sulfur

unfortunately I could not produce an expectable veg formula without the addition of magnesium nitrate to get the nitrogen up
(using calcium nitrate would put to much calcium in the mix)
per gallon
1.5 grams calcium nitrate
1 gram magnesium nitrate
0.5 grams Epsom salt
1.5 grams mix

Thanks for the input fellas, greatly appreciated!!

I could keep using my 5-11-26 to make veg nutes, and buy the 4-20-39 for making bloom nutes.

They've been at it for over half a century.

I'd love a copy of that spreadsheet if you got one spare??

I've manually built my own profile and "in-house" stocks. I'd love to run it through this and share the results.

I got it from the place I buy my salts by email

im not sure if its on the site for down load

I posted the links to his site

maybe if you get some of his gear he will hook you up idk

youll need excel

OK cool, I also shop with custom-hydro. I'll drop Byran an email and see if he has it.

Thank you thank you!, I ordered up everything you suggested @im4satori. Do you recommend anything specific to keep the system sterile?

Which makes the better bloom mix, and why?

Ease of mixing aside, at least.

let me post the 2 side by side

give me a few

after spending some time im realizing you could mix the 5-11-26 almost as easy and with better numbers

this is hotter than I run but it can be diluted

veg
2grams mix
2grams calcium nitrate
2grams Epsom salt

bloom N: P : K ratios 2: 1 : 3
2grams mix
2grams calcium nitrate
2grams epsom salt
0.5 grams mkp

late bloom (last 2 weeks) N: P : K ratios 1:1:2
2 grams mix
1.25 grams calcium nitrate
2grams Epsom salt
0.5 grams mkp
