I assume all these formulations with a calcium as high or nearly as high as the nitrogen are intended for growing in soil.


is this the gentleman that has been banned almost everywhere? If so, I have some questions on your bloom recirc formula :)

have been banned from some sites for calling moderators on their bullshit and for being tactless

I run lower calcium on drain to waster large chamber aero air atomized and find that I can run nutrients with a much lower calcium in relationship with nitrogen then you (Spurr) recommends or that is supplied with mot nutrients supplied by GH and mj specific nutrient manufacturers. As I have a very large number of hair roots I have more than enough root tips to take up calcium while using much less calcium. It also greatly lowers my nozzle clogging problems.

well, glad you are here then! fuck'em if they can't handle what you are saying.

i posted a question on the high n myth thread in regards to your bloom recirc formula

"mj specific nutrient manufacturers"

I thought you would be the least person who use this expression.

How else would you describe Fat Mikie's (AN) firm or the others who tout that they formulate their nutrients specifically for mj growing?

Some of AN's products claimed to be cannabis specific (Kushie Kush) but officially they don't even mention the word cannabis on their other products.
Using shady terms like "our highly profitable plant" is not necessarily cannabis.

Other than AN I haven't seen a company who claims to sell nutes designed for cannabis. They try to suggest it but never claims it directly.


Anyway my point is:
AFAIK no real research has been done so far to determine the optimal nute levels for drug type cannabis plants so anyone who claims to sell nutes designed for cannabis lies.

GW Pharma might have done trials but it's not published.

The only logical reason they suggest and do not specifically state their intent is to provide nutrients for mj growing is purely a method of skirting Amwerican laws prohibiting the production and sell of products specificlly produced/sold for the production of a controlled substance. Even Canada will extradite persons to the US for prosecution of drug crimes if the US presses (i.e, Narc Emerick).

What, you mean the manufacturers of implied mj specific nutrients might be dishonest in their advertising geared towards convincing mj growers that their products are best for growing mj. Oh, my trust is shattered.

If that is the case, what about Kushie Kush?
AN specifically state it's for cannabis.

Fat Mikie seems to ignore the possible consequences of selling what is determined by US federal drug laws to be illegal as did Emerick who is now wasting his life sitting in a US federal prison after Canada willingly extradited him to the US for trial for breaking US controlled substance laws.

What I don't understand is: why just 1 or 2 products are officially claimed to be for cannabis cultivation, why not the whole line?

Am i the only one thinking AN is about as far from DIY nutrients as it gets? Or maybe not. You need 14 bottles from them to get all your nutrients. That's kinda DIY ;)

AN (Fat Mikie's firm) is very heavy into selling snake oils. He would sell snake piss or monkey etc as a special supplement if he could get a constant source that was cheap. All his products have grossly high market ups. Even higher than the others firms rediculus mark ups.

because even big big mike knows there is a limit on how full of shit you are allowed to be?:)

Someone in this thread asked for an example of what I think is a good mix, using dry salt compounds. Below is an example ...

I was hired recently to create a few cannabis specific fertilizer formulations for various stages of growth, EC, source water, etc. Initially the person that hired me asked me to use Peter's Professional Hydro-Sol (5-11-26) as a base.

Below are some excerpts from something I wrote about this mix and making stock solutions in general, etc. I used HydroBuddy to make the following mix, and I am posting a version that assumes pure source water (i.e., doesn't account for ions as EC or elements, in the source water). I also didn't account for P from phosphoric acid, a common pH down product.

Below is a screen shot that lists the salt compounds used, not shown is 0.361 grams of boric acid into mix B
. And how to mix bottles A, B and C. Use of A, B and C is 10 mL per liter of fertigation water, each.

The person that hired me grows in Sun Shine Mix #4 using drain-to-waste on a drip ring and timer; flushed weekly with plain water.

I.) Notes:

...

5) After messing around with lots of mixes, I found the perfect mix of inexpensive salts. The mix provides N-P-K of 3-1-4 and K-Ca-Mg of 3.2-1.84-1 [i.e., 4-3.2-1.25, what you requested]; as well as providing sufficient Si, NO3:NH4 ratio of 14, etc. The following are the salts I used, including those you don't yet have. Using the following salts, excluding the micro's, increase the accuracy of the ppm calculations a great deal, which is a very good thing. Using all of the following salts I was able to reduce the price per unit, too:

...


--> I attached two screen shots, the first one, "complete_mix_a", shows how to make the stock solutions (mixes) A, B and C. Ex., how much of each compound to add to each gallon to make stock solution (not shown is 0.361 grams of boric acid into mix B). That screen shot also shows the elemental profile by ppm, providing exactly what you asked for. The EC shown is 1.6 mS/cm, which is the EC of the fertagation water after the specified volumes of mix A, B and C are added. If we include the EC of your source water, i.e., 0.4 mS/cm, the total EC for your fertigtion tank will be 2.0 mS/cm; and I believe that is the EC you requested, correct?


II.) Mixing notes for stock solution:

a) when weighing dry salts use two scales: one that measures down to 0.001 gram and is accurate to 0.001 gram (jewelry scale for micro-nutrients), and one that measures to 1 kilogram and accurate to 0.01 gram, better yet 0.001 gram. Following is an example of en Ebay search for 0.001 gram scales: http://shop.ebay.com/items/?_nkw=sc...pt=1&_sadis=&LH_CAds=&clk_rvr_id=248929254212

b) when measuring liquid volume, ex., for Silo-Tec potassium silicate, use a good graduated cylinder, and a syringe for single mL and less than mL measurements. However, we can find the specific gravity of Silo-Tec and then use weight, instead of volume, to measure out Silo-Tec for mix C.

c) fill jug for mix A with 1/2 gallon distilled or deionized water, then add the salt compounds for mix A, shake and dissolve with each addition. Then add the other 1/2 gallon distilled or deionized water and shake.

d) do the same as above (re: mix A), when mixing B, and C.


III.) Mixing notes for fertigation tank (working solution):

a) fill tank to 1/2 volume with source water needed, ex., if you need 100 liter, fill with 50 liter.

b) add mix C (potassium silicate) at 10 mL per liter of total tank water and mix/agitate to fully dissolve (wait a couple of minutes), then adjust pH.

c) add mix A at 10 mL per liter of total tank water and mix/agitate to fully dissolve (wait a couple of minutes).

d) add mix B at 10 mL per liter of total tank water and mix/agitate to fully dissolve (wait a couple of minutes).

e) adjust pH

No worries, glad to help. Soon I will post mixes not using Peter's Professional Hydro-Sol. As well as mixes for (1) veg and pre-flowering; (2) mid flowering; and (3) late flowering.

All of those salts can be found at Custom Hydro Nutrients and J.R. Peter's Lab, I can't recall if one can buy everything at just Custom Hydro Nutrients (I think boric acid is missing, etc.). Oh yea, the silica product, "Silo-Tec" is from Grow More and inexpensive, it's the same things as Dyna-Gro "Pro-TeKt" (i.e., 3% K and 7.5% SiO2; IIRC).

Please note that the mix above, and those to come, are not yet tested. But they will be within the month. The mixes are very sound, based on many cannabis tissue assays (with many more to come, well over a few hundred!) as well as testing by myself and others, re: my GH mix(es) and custom mixes by many others.

Oh yea, after a lot of testing by myself and others on cannabis, I can write that N-P-K relativity (by ppm) of 3-1-4 works very well from veg to harvest, as well as K-Ca-Mg of 3-2-1.

P.S. According to a few authoritative academic resources (ex., UC Davis), to find N-P-K or K-Ca-Mg by ppm (what is sometimes referred to as a ratio), one would do the following:

for example:

  • N = ppm of total N (ammonicial + nitrate)
  • P = ppm of P
  • K = ppm of K
  • L = element with lowest ppm; in this case let “L” represent ppm of P.

where:

  • N = 150 ppm
  • P = 50 ppm
  • K = 200 ppm
  • L = 50 ppm

then:

  • N/L = 3
  • P/L = 1
  • K/L = 4

Thus, the relativity of N-P-K by ppm is 3-1-4.

I can't wait to see what you post! wouldn't it be quicker to just provide n-p-k-mg-ca values versus doing screen shots?

i do direct addition so it is a bit easier versus making concentrates.

@ 1971,

I like using screen shots because I think they are more readable and legible to people, myself included. I can pack in many more data in a screen shot, and still make it legible (ex., spreadsheet), than in a post; ex., by use of tables, graphs, etc.

Here is the same mix as above, but it's made for direct addition to 100 liters, not shown is boric acid at 0.095 grams:
