    If they have that or 4-20-38 or thereabouts, again with hydroponic micronutrients, that will also do well. The other two salts to get are calcium nitrate and magnesium sulfate, aka epsom salt. Yes, mag and sulfur are supposedly included in the micros in the mix, but my resin production improved when I began adding epsom salt so I recommend it.

    @ttystikk are you still using this recipe? If so, is it working well? I have been using Jack's hydro 5-11-26 at approximately the 3:2:1 ratio with good results, but am considering changing it up since the plants are flowering.

    Also (dumb question here), you are using the ratio by mass, correct -- not volume? i.e., you are weighing the nutrients, not going off teaspoons/tablespoons.

    on behalf of ttystick (hope you don't mind)

    the jacks pro is basically the same thing as the 5-11-26 hydro special

    no real difference except the jacks doesn't require the Epsom salt cuz its already in the bag
    (speaking of jacks pro, not the other available formulas by jacks)

    switching from the 5-11-26 hydro special to jacks pro ....well that's like trading oranges for more oranges

    youll get the same thing
    (except the jacks pro has a bit more magnesium than the hydro special)

    ...and yes every thing should be weighed in grams

    So, since I am using Jacks, should I just not use any epsom salt? 2.5 Jacks:2 Cal Nit:0 epsom:0.5 mpk?

    is it for sure "jacks pro"? and not jacks classic or something like that?

    mixing it that way will give you a hot mix that you can dilute to your desired EC/PPM

    its a versatile ratio of NPK that could be used from start of bloom until finished without changing it

    you could mix it the same way and just eliminate the mkp for veg

    if you want to leach N in late bloom (some do, I do not) you can drop the calcium nitrate down to 1.5 grams per gallon and keep the rest as is

    examples
    per gallon
    veg
    2.5 grams jacks
    2.5 grams calcium nitrate

    transition

    2.5 grams jacks
    2 grams calcium nitrate

    bloom

    2.5 grams jacks
    2 grams calcium nitrate
    0.5 grams mkp

    late bloom leaching N option
    2.5 grams jacks
    1.5 grams calcium nitrate
    0.5 grams

    Im not sure if this is Jack's Pro, or whatever. It is labeled as 5-12-26 Hydroponic

    I think he may have meant he was thinking of switching to a different ratio in flower and not so much Nutrient Manufacturer.

    Exactly. Im about 4 weeks into flower and have been using the same 3-2-1 ratio (18 grams of Jacks, 12 grams cal nit, and 6 grams epsom per 5 gallons of water) since they were seedlings so figured I would look into modifying the nutes to better match the flowering requirements. Yes, my mix is on the hot side but the plants have no burn and look great. I just mixed up some 2.5-2-0-0.5(mpk) and put in in the reservoir.

    Also, an fyi in case it matters: I am growing in coco/perlite at 2:1 ratio, auto watering with blumats and only get runoff when a random blumat messes up and floods a plant. This is my first time using coco, blumats, or Jack's but it has been working out pretty nice. I have an air pump with 2 stones in my 13 gallon reservoir to keep the nutes mixing continuously so hopefully no precipitate to plug my blumats. These plants are in a 5x5 with about 1000 true watts (measured AFTER the power supplies) of led strips -- ~620 watts over head and ~360 watts of side lighting.

    I’m trying jacks. I have one girl in an experimental “passive plant killer” method and the rest in my regular coco pots.

    One of my girls is an oddball accidental cross breed of gg4 and bubba kush- could be interesting but what a light feeder! I fed her in veg so light most plants wudda starved she exploded! First feed w jacks got nitrogen claw on her- the other two gg4 look spot on perfect- she’s looking better already with a water only watering going to do a light flush nothing drastic.

    I’m wondering would you guys say back off the calnit or just dilute the standard 3:2 mix down equally? I will start 321 next feed.

    Thank you for the great ... and long read! It’s been educational saying the least.

    @ttystikk, went to order some of the formula you use from Hydro-garden and was told it’s been discontinued

    @im4satori, would this stuff work?
    They suggested their new 4-20 (clever) formula. It’s 4-20-39

    https://hydro-gardens.com/product/420-hydroponic-25lbs-bag/

    I was hoping that I could get some thoughts on these nutes as I really want to try this stuff out :)

    You can get peters 25lbs 5-12-26 from amazon for around 70$.

    You don't have to add epsom/mag sulfate with jacks 5-12-26, with hydro gardens 4-20-39 you do.

    The main reason I was looking at the Hydro 5-11-26 was that it had better micros according to ttystikk plus MgSO4 is cheap locally @ under 45 cents a lb :).

    It is true that epsom is very cheap, however I'll take simplicity over cost, to a certain extent of course. The hydro gardens 5-11-26 did have more micros than peters 5-12-26 and the hydro gardens 420 mix has more micros that either of those.
