    Pour salts in bottles:

    Part A:
    Calcium Nitrate
    Potassium Nitrate
    Iron DTPA (10 or 11%)

    Part B:
    Monopotassium Phosphate
    Magnesium Sulfate
    Manganese Sulfate
    Sodium Borate
    Zinc Sulfate
    Sodium Molybdate

    Fill the rest of the bottles with RO/distilled water.

    Potassium Hydroxide flakes if you need pH up. (caution, poison! clean hands after using, bad for eyes)
    Nitric acid, phosphoric acid, or sulfuric acid for pH down. (bad for eyes! don't drink. Don't pour in eyes or hands. Wash hands after handling.)

    Get HydroBuddy:
    First pick the substances you're using by hitting the "Substance Selection" button.

    Next, pick a built in formulation so you have a good base recipe to work with. I picked a recipe from University of Florida. (keep things simple for now)

    formulations.jpg

    Set "Stock Solution Volume" to 1, check the "liters" radio button, Solution preparation type A+B, and concentration factor 400. Keep the calculation type as "input desired concentrations". Set the ppm of Cu to 0 since we're not using a substance to provide Cu. Finally, click "Carry out calculation"

    Now click the results tab and it will show you how much of each salt to put in each 1 liter bottle.

    Now these stock solutions can be used in a 1:1 ratio, 10mL of each for every 1 gallon of final reservoir solution. It has an NPK ratio of 1: 0.74: 1.44. Label the bottles with how much of each salt you put in it so you can remake the bottles without hydrobuddy next time.

    I get most of mine from cropking.com, but there are a lot of places online, including amazon and ebay. I got my last 10lb of potassium nitrate on ebay because shipping was so expensive for that one item on cropking. I think the ebay seller must have been breaking the rules or something, but whatever, cheap shipping! (the package came literally leaking potassium nitrate out of a hole)

    They should be pretty easy to find in small quantities. It's also possible you might find 50lb bags if there is a local agricultural supply place near you, although I've never been able to find one of those. A 50lb bag of calcium nitrate on cropking is like 35 bucks, but shipping 50 pounds is very expensive!

    How long have you been making your own nutrients? From your experience has it turned out to work; "not so well", "the same", or "better" than commonly available brands and blends of other nutrients such as Advanced Nutrients, General Hydroponics, Canna and so forth?

    I started making my own hydro nutrients in 2009. It works the same or better (because I'm a better grower now). It's the same thing. These are the ingredients used in AN, GH, Canna, etc.

    I chose to show that Univesity of Florida recipe because it's the closest to my own formula, which I have great success with. I don't miss a single thing from GH. I did not want to show my own formula on the first post because it's designed for hard tap water and might not be ideal for RO growers. I have made 19 iterations on my formula since 2009.

    The recipe for the RO water would require for one to implement a calcium magnesium supplement into their regime, correct?

    Pending on amount you want ?? source out your local chemical company will have most in liquid form 5 gallon form i used to get 2 skids a year of calcium nitrate it works good for lawns as well lol although you may have to cut 2 times a week just make sure to water the lawn big time before and after or you will wake up to blonde lawn haha if you did it right Everyone will envy your lawn i even made money when neighbors asked me wtf i use i said 50 bucks and i will give you one application haha

    1 liter of A and 1 liter of B of that U of florida mix i showed costs $2.10, and that's factoring in the rate I pay for nutrients in small quantities. For a warehouse grower, it would be more like $0.50-$1.00 for BOTH a liter of A and B stock solutions.

    It barely takes me any time to measure out those nutrients. I just look at the list written on the bottle, and measure out what's on the list, and pour the things in.

    A+B stock solutions are really convenient because you can use an equal part of A and B and run out at the exact same time.

    Basically it would involve adding more calcium nitrate. My tap water is very high in calcium carbonate. I don't think it has much magnesium.

    I still have the same 50lb bag of calcium nitrate I got in 2009. There is no waiting, just going to get the bag... For 1 litter bottles of H&G, you have to go driving to a hydro store.... or wait for them and waste time and money!!

    Also, it takes the same amount of time to make a 1 liter stock as it does a 5 gallon stock. The argument that it takes too much time makes no sense. You could just as easily say it's too inconvenient to cook because you have to get all the ingredients and waste all that time cooking. (it takes longer to cook a meal than it does to create A+B stock solutions)

    You should check out my thread on reverse engineering nutrient blends. Or just visit the website I started to keep track of all the information.

    It's not a waste of time and money when you are spending less than half the cost of anything at a hydro store.

    Gees, could we get some punctuation?

    Anyway, keep checking back. I'm constantly adding more recipes. And yes, H&G is on the list.

    What do you mean by "one day it may be 30 next day its 60"?

    The laws behind fertilizer labeling are pretty straightforward. But, I think the "few other things" that you are talking about are things like B Vitamins, plant hormones, etc. While they are harder to pin down, it is still possible.

    Additionally, I do plan to sometime soon have an online store with affordable raw materials. And yes that includes fulvic and humic acids, plant hormones, etc. I think you would quite surprised to learn that you can create all of these for a lot less than you expect.
