    The 5-11-26 plus micros mix. It looks like they've whittled down their choices quite a bit on the website.

    I'd get the hobby and then add a bit of MKP (monopotassium phosphate) as needed for bloom. Cheaper, easier, more flexible and controllable this way.

    comparing the two mix options

    the 5-11-26 compared to the 4-20-39

    if your mixing the 5-11-26 like this for example
    per gallon
    2 grans calcium nitrate
    3 grams mix (5-11-26)
    1 grams Epsom

    that yields

    112 ppm N
    38 ppm P
    171 ppm K
    50 ppm Mg
    100 ppm Ca

    if you mix the 4-20-39
    per gallon

    2 grams calcium nitrate
    2 grams mix (4-20-39)
    1 grams Epsom

    that yields
    103 ppm N
    46 ppm P
    171 ppm K
    50ppm Mg
    100ppm Ca

    mix is used atr a rate of 3grams per gallon vs the 4-20-39 which is used at 2 grams per gallon

    therefore you can expect the micro nute amounts and iron to be higher when using the 5-11-26 mix comparatively

    another thing id prefer
    the 5-11-26 mix is easier to add mkp bloom booster since you can easily drop the 5-11-26 mix portion down to 2 grams and add the mkp which will put your k back to the same place

    for example

    calcium nitrate 2 grams
    2 gram mix (5-11-26)
    1 gram Epsom
    0.75 grams mpk

    108 ppm N
    70 ppm P
    170 ppm K
    42 ppm Mg
    100 ppm Ca

    you can see this mix provides more P if you so desire it

    having said all that

    the jack pro I linked above can be mixed exactly the same way as the 5-11-26 hydro special but you wont need the Epsom salt since theres more Mg as a % in the jacks than the is in the 5-11-26 mix

    3 grams jacks pro mix
    2 grama calcium nitrate

    119 N
    41 P
    171 K
    50 Mg
    95 Ca

    or if you want the extra P in late bloom

    2 grams jacks pro
    2 gram calcium nitrate
    0.75 grams mkp
    0.5 grams epsom

    106 N
    73 P
    170 K
    46 Mg
    95 Ca

    I like using epsom salt for the extra sulphur.

    the jacks ends up yielding the same amount of sulfur as the 5-11-26 mix

    the Epsom salt is already In the bag of jacks so your still getting the same amount of sulfur either way

    jacks
    3 grams mix
    2 grams calcium nitrate

    yields 65ppm sulfur

    hydro mix
    3 grams mix
    2 grams calcium nitrate
    1 grams Epsom

    yields 65 ppm sulfur

    its basically the exact same mix except the jacks already has the Epsom salt in the bag

    im sure if you look at the % amounts listed on the bags

    the jacks will be the same as the hydro mix 5-11-26 only it (the jacks) will have a higher % of magnesium and sulfur

    if I was you

    id get the jacks pro, some calcium nitrate, and some mkp and Epsom salt
    per gallon

    veg full strength

    2.5 grams jacks
    2.5 grams calcium nitrate (green house grade yara)
    0.5 grasm Epsom

    transition full strength (first 2 weeks bloom)
    3 grams jacks
    2 grams calcium nitrate

    bloom
    jacks 2 grams
    calcium nitrate 2 grams
    mkp 0.75 grams
    Epsom 0.75 grams

    heres how those mix ratios translate into numbers

    veg
    132 N
    35 P
    143 K
    54 Mg
    71 Su
    119 Ca (a little high)

    transition
    119 N
    41 P
    171 K
    50 Mg
    65 Su
    95 Ca

    bloom
    106 N
    73 P
    170 K
    52 Mg
    Su 68
    Ca 95

    now
    examine the numbers closely

    notice how the N slowly drops and the P rises when going from veg to transition to bloom..and the K goes up for all of bloom.... that's about as perfect a ratio as you can get

    the calcium, magnesium and sulfur stay about the same


    if a person wanted to they could likely get away with feeding the transition formula only for both veg and bloom

    comparatively

    here are the numbers for GH floranova 1part grow and bloom

    bloom at 10mls per gallon

    106 N
    92 P
    154 K
    Mg 53
    Su 53
    Ca 106

    grow at 7mls per gallon

    132 N
    32 P
    154 K
    28 Mg (low)
    37 Su
    74 Ca (low)

    this grow formula will likely require calmag and Epsom unless you have hard water

    add 3mls per gallon calmag and 0.5 grams Epsom salt

    145 N (high)
    32 P
    154 K
    50 Mg
    53 Su
    99 Ca

    I've been doing the 2.5g Jack's 2g calcinit and 1g Epsom per gal in veg per Dr. satori's orders.

    Rdwc is exploding. Roots have almost filled up the 12gal totes. Getting some weird leaf twisting on new growth. Not sure if it's due to the 1.0EC it's at. Hard to keep up with them. I might have to bump them up to 1.4EC. been doing my usual 1.2EC.
