    Add rhizotonic, cannazym and say silica at my preferred measurements to my nutrient mix. Also my micros, mineral matrix say.

    Then add a concentrated jacks 3-2-1 ratio to bring my ec up?

    Think that's it. What measurements of micros would you recommend?

    Hoping it's low at 30 a litre lol

    I used 2 ml Mineral Matrix to 5 gallons of plant ready nutrient solution. That's only because Jacks is short on iron and micros as a cost saving measure.

    That's really why I recommend hydro-gardens. They aren't scared to talk about Cannabis because they're based here in Colorado. Bonus!

    I just use 3-2-1 and nothing else and it works like a charm.

    i just ordered a lb of jacks classic no.1.5 20-10-20 citrus and 5lb of potassium sulfate.. was told a 1/4 tsp per gallon,, then to weigh it out,,, will i be ok just using the 1/4 tsp or do i really need to weigh it??

    scoop out as much as you need for your reservoir then weight it and see how close the numbers are...

    I would weigh it

    it takes very little to make a big difference... potassium sulfate has 52% potassium so its very strong

    youll need a good scale for about $50 +/- that measures grams several numbers below the decimal point
    like a jewelry scale

    a kitchen scale wont measure increments that small

    that's my opinion......
    unless your medium happens to be soil that buffers then you might get away with measuring it 1/4 tsp

    Instead of needing that kind of precision, I just mix larger batches that I'll use up in a few days. Just give it a stir before using.

    Always nice to see you!

    that works also

    when measuring a blend like the hydro special 5-11-26 its more important to mix larger amounts
    because your dealing with a blend of several salt minerals in the same container so small measurements are unreliable in precision

    with a single element like potassium sulfate a good scale is fine to mix smaller amounts but in a blend its best to mix larger batches for sure

    Since you're here, what do you think of switching to a dry nutrient mix consisting of 4-20-38 with micros? It too would be mixed at equal weight of calcium nitrate and half that weight of mag sulfate.

    the 5-11-26 special has magnesium and sulfur in it also

    does the
    4-20-38 have magnesium or sulfur in it?

    I assume the micros are roughly the same

    at a glance it looks good

    2grams calcium nitrate
    2garms mix
    1gram Epsom salt

    N103
    P46
    K167
    Mg ?
    Ca 100

    if we assume for a second that the 4-20-38 has the same % of magnesium listed as the 5-11-26 (3.1% Mg)

    that mix would yield
    42ppm Mg

    How do you guys deal with providing iron over the long term to soil?
    In the aquarium business, we have to fertilise plants with a daily or every other day iron dose, as the iron becomes used up or unavailable very quickly.
    Does soil behave the same?

    Is anyone who uses Jacks aquagold finisher, willing to list the nutes in it. I couldn't find the label anywhere.

    The iron used in hydroponic nutrients is chelated to remain in solution.
