    I think you need to start thinking for yourself. You have all the Information to base your Choice on^^

    That Ferti 08 could replace Yara Azure easily, has very high(8,5%) S though.

    Ammonium should be less then 20% of total Nitrogen. Higher Ammonium Content is more suited to Soil in General.

    Ammonium will reduce your Media┬┤s PH over Time while Nitrate will increase it.

    Cannabis Specific Fertilizers usually have 10% Ammonium of Total Nitrogen.
    Canna for example has these Ratios in their Hydro/Coco Fertilizers

    36% K is fine as long as you dont go overboard with pk boosting while not providing extra Ca/Mg.

      On Topic of Ammonium,

      According to Jeff Lowenfels Teaming with Nutrients, Annuals Plants like Cannabis prefer their Nitrogen in Nitrateform, which also implies Bacterial Domination in the Media.(yet we are constantly trying to get Fungus to settle)

      Some Vegetables are supposed to Flower worse with considerable Ammonium present others benefit from it.

      I have no Clue in which Range Cannabis falls but i see Hydro Companys taking the 1/10 Ammonium of Nitrogen Route mostly.

      I noticed a favorable Flowering Response when applying Mono Ammonium Phosphate in the first Week of Flowering after Switch. If this is because of the extra NH4 applied i cant tell.
      Applying MAP in Rooting/transition is a very old Greenhouse Practice though.

      Looking for Comments on this.

        In Hydroponics: A Practical Guide for the Soilless Grower, J Benton Jones Jr. says this ratio keeps the pH from drifting.



        I don't add extra MAP at transition because it doesn't follow tissue sampling I've seen. A bump in calcium does.

          Any guides for using the Masterblend line with cannabis?

          Got the tomato MB(4-18-38), CalNit(15,5-0-0/18,5) and epsom salts. Will get the Fulvic soon enough if necessary.

          Currently growing in soil+coco organic mix.

            That Book is a good read, i especially like that the author states multiple times troughout thw book, that in Soilless growing what you are feeding is not what the Plants are getting, cause regardless of Ion Exchange Capacity of the Medium the precipates of prior feedings will allways affect your current feeding. I think thats a point Poeple are often missing.

            Would you say that Tissue Samples allways give the right Picture of what a Plants need?

              I'm fairly certain that MB is 3/2 and 3.6/2.4 just like Jack's.

              That's why watering to run-off is important. It's why recirculating or DTW coco is popular.



              Tissue samples are the best approximation of how to feed your plants at a certain time.



              I've never gotten into testing micros. I'm interested what a Calcium Boron bump at transition would do.

                Thank you for this thread and for the information you are willing to share. I recently switched to MB with no supplements so far. I'm in DTW coco, fairly dialed in environment.


                If I may, a couple of questions.


                If flower set/ stretch happens in a much quicker time than usual, do I discontinue the metasolate at that time?


                After weighing the hammerhead ingredients, are they mixed in solution? Ratio? Also, application rate?


                thank you again

                  I usually discontinue Metalosate when the plants start to put on flowers. The timing of extra calcium is the important aspect.



                  The DIY hammerhead is used at 1g/gallon. You can mix it in whatever liquid concentration you would like.

                    I'm sorry to sound so thick headed, but still not clear on the hammerhead.
                    Do I mix dry ingredients together, then 1g/gal?


                    I appreciate your response and patience for silly questions.

                      Yes, that's it.

                        I actually interperted the tissue sample in the opposite way. looks like there is a slow and steady increase in NH4 form N throughout the enitre cycle, whereas NO3 form peaks out mid flower before dropping. i wonder if the plant starts to prefer more NH4 during the later part of the cycle because it is more rapdily converted into protein, so less gets stored? in any case as mentioned by ADHDgrower ive also started supplementing low levels of MAP during transition and into early bloom, only about .2 g per gallon, so extra ammonium levels are below 10ppm. cant say ive seen much of a difference yet but we'll see.


                        **edit, was thinking about it and the tissue sample may not necessarily correlate to feed recommendations as far as N form goes as NO3 is converted into NH4 and subsequently proteins. so the increasing level of NH4 in the tissue sample could simply be a result of plant physiology preferentially converting NO3 storage into NH4 through the course of the growth cycle.

                          So if you have a fixed base nutrient, the plant along with fulvic acid creates and uses what it needs without major supplementation. Seems like the tissue samples work to me.

                            I did some early testing with MB to see how mixing works and pH behaves. Surprised to see it really has to be mixed like MB say, first MB, then MagS and finish with CalNit(parts mixed 2:1:2). If the mix is not 100% diluted, it will leave some residue on the bottom, so a bit of care is essential to mix it as it should be.

                            Also the pH seems to be around 5.5 even at very high ec(in mixing bottle), so if the water is not too acidic(mine is usually around 7) the mix will not need extra pH adjustments.

                            So far all looks good, now let's see how plants like it.

                              absolutely, I very much appreciate you sharing all this information. im relatively well versed on nutrient management but I suppose i never viewed it as such a timing dependent thing.



                              also wondering if you have any knowledge on the use of polyphosphates with canna. found the product "Haifa grow clean polyphosphate" 5-31-40, and was curious about using it, but I wasnt able to find any information regarding its use for something that is inhaled. it seems to be Na and Cl free. I can't think of any outward reason that it could be harmful, but I would prefer not being the guinea pig who finds out its unfavorable for some reason.

                                Polyphosphates are used with alkaline water to prevent scale with irrigation in products like Drip Clean. I'm sure it will work as a fertilizer, but it typically has a very specific function for the cost.
