480 ML Distiled water
0.7g Ascorbic Acid
0.3g Potassium Sorbate

Add 3.569 gm of NH4Cl 53.4915 g/mol
0.5 ppm Cl
0.19 ppm N

Add 11.665677047 gm of Urea
N 1.15
NO3 5.09105

Add 2.078953227 gm of KH2PO4
K 0.126227455
P 0.1
PO4 0.30662771

Add 9.532439003 gm of K2SO4
K 0.904
S 0.370696891

Add 18.713697077 gm of MgSO4.7H2O
dGH 0.089982251
Mg 0.39
S 0.514533568

Add 2.968130026 gm of DTPA Fe (11%)
dGH 0.006928714
Fe 0.069

Add 1.419525 gm Mn EDTA 13%
Mn 0.039

Add 0.18927 gram Cu EDTA 15%
Cu 0.006


Solution #2
500 ML Distiled water
0.5g Ascorbic Acid
0.2g Potassium Sorbate

Add 0.530 gram of Na2MoO4.2H2O
Mo 0.002
Na 0.000958304

Add 2.706 gram Boric Acid (H3BO3)
B 0.004

Add 0.048 gram NiCl2*6H2O
Ni 0.0001

Add 0.0631 gram ZnEDTA 15%
Zn 0.002

Last Stage: Add 20 Ml from solution #2 to Solution #1, which will complete 500 ml solution, dose 20 ml per 50 gallon, each dose will give you the following PPM below. Solution #2 was made this way to improve accuracy as gram scale cannot measure such a low levels accurately. i would also advice to add KH2PO4 in the very end after you let the solution sit for few hours just to be safe from precipitate

Final Solution:

for those who want to avoid using NH4CL, you can use the following recipe, all you really doing here is replacing Nh4Cl with KNO3 and KCL

Add 12.857457452 gm potassium Chloride
Cl 0.5
K 1.425050269

Add 6.489452669 gm of KNO3
K 0.53036358
N 0.19
NO3 0.841113333


N 1.34 (5.93 NO3)
P 0.10 (0.30 PO4)
K 2.98


Example of My method (do not use this recipe, this is just for read only):
Add 0.129 gram of H3BO3 to your 500 ML container. Each dose of 10 ML will raise B 0.006 ppm in your 20 gallon tank tank.
B 0.006
Add 0.033 gram of ZnSO4.7H2O to your 500 ML container. Each dose of 10 ML will raise Zn 0.002 ppm in your 20 gallon tank tank.

S 0.098087698
Zn 0.002

500/10 = 50
solution #1 50x0.129 = 6.45 gram of H3BO3
solution #2 50x0.033 = 1.65 gram of ZnSO4.7H2O
Solution #3 400ml, adjust if need to

Add 2.40 gm of DTPA Fe (11%) to your 500 ML container. Each dose of 10 ML will raise Fe 0.07 ppm in your 20 gallon tank tank.
dGH 0.007029131
Fe 0.07

Add 14.970957662 gm of MgSO4.7H2O to your 500 ML container. Each dose of 10 ML will raise Mg 0.39 ppm in your 20 gallon tank tank.
dGH 0.089982251
Mg 0.39
S 0.514533568

Solution # 3 this is the final solution, add 2.40 gram Fedtpa 11%, add 14.97 gram Mgso4, add 10 ml from solution #1 and #2, this adds up to 420 ml solution, add 80 ml Di water to fillup till 500 ml solution, now you have =
0.07 ppm Fe
0.04 ppm Mn
0.002 ppm Zn
0.006 ppm B


Please do not copy or sell this Recipe, its only for my fellow hobbiest

What is the logic for using so much, ratio-wise?
Usually beneficial for red plants, tested the same dose even as CuSo4 with shrimps etc and completely safe, no shrimp deaths occured during the test for over 2+ years. This ratio was our standard ratio, almost similar to TPN, we based our recipes based on TPN and modified them further when needed, so I thought I share the orginal recipe here so people can benefits from it. If people are afraid of the NH4 and Urea I will post another recipe for those who might be interested at their request.

Why no calcium?
Unfortunately calcium cannot be mixed in the solution, it will react with anything that have so4, it doesn't matter what source of calcium you use, it will react, for example cano3 with still react with k2so4, calcium will also react with po4 to form crystals in the solution. Plus many of us have calcium in our tap water or we add though other ways to changed water, it is only possible to make such a solution if solution is very acidic and ppm numbers are very low and source such as cano3, anything that ends with cl, no3, kcl, or other chloride based chemicals are used, so you have to avoid anything with so4 and co3 in the same solution. Above is really an all in one solution which other trace don't add, such as Na, cl, Ni etc

So you forgot to tell anyone that this will not work in water without calcium, such as a tank filled with RO water and an inert substrate. Also I suspect it won't work in a tank with low boron or zinc levels in tap water. Most people have to add a lot more (including burr740). IN short you customized your fertilizer to your tap water. So it may work for some people and may not work for others.

Perhaps calcium might be EDTA would stay soluble and not react.

Also what is your source for the cu, mn EDTA? I looked for those some time ago and didn't find any.

Thanks for posting this. Interesting mix. So this is based on TPN at the start. I was wondering if you tried just Fe-EDTA instead of DTPA ? And if you tried all traces in chelate form (all that are possible of course )?

Thanks again.

Regards,
duky

It helps when comparing other fertilizers to use a guaranteed analysis. Here is the analysis of the fertilizer you listed...
Code:
N	0.8% (NO3 3.5%)
P2O5	0.22% (P 0.095%) (PO4 0.29%)
K2O	1.18% (K 0.98%)
Mg	0.37%
S	0.84%
Fe	0.065%

Mn	0.037%
Cu	0.0057%
Mo	0.0017%
B	0.0039%
Ni	0.000095%

i don't think i would debate on this one as my philosophy is different about Nutrients. Calcium is almost always present in our tap water, it's a common sense that one must add some calcium when using RO water, far as Burr recipe goes, that is a completely different approach, i have also shared some of the pictures in one of the thread while using NON chelated traces with the Help of Zorfox couple years back. i posted this recipe so people can understand how to DIY pretty much everything, i have posted the link to calculate and how to calculate % as well.

"So you forgot to tell anyone that this will not work in water without calcium, such as a tank filled with RO water and an inert substrate. Also I suspect it won't work in a tank with low boron or zinc levels in tap water."


the problem with this quote is that, you already came to the conclusion, one has to try the recipe before making conclusion. also, am sure people are aware of the Ammonium being added through NH4Cl as well, this one we can replace with something else, we could further replace the Urea as well at request by the others, am actually thinking about posting that soon as possible.

here's something for you if you like higher traces, this is Tenso Cocktail Recipe, this can work for those who use tap water and add good amount of NPK as well as Ca and Mg:

Trace/Fe Solution, 500 ml, 20 ml per 50 Gallon

Solution # 1
Add 4.301 Gram of Fe DTPA 11%
Add 0.379 Gram H3BO3 (Boric Acid)
Add 2.438 Gram Mn EDTA 13%
Add 0.441 Gram Zn EDTA 15%
Add 0.441 Gram Cu EDTA 15%
Add 3.075 gram Ca EDTA 10%



Solution #2 ( Make this one Seperate from Solution #1, this is because there is no way you can measure very low levels of gram on your scale, add MoO3 in 500 Ml solution and once done, add 20 ml from this Solution to Solution #1 before filling the Solution # 1 all the way up to 500 ml or make the solution # 1 with 480 Ml water and add 20 Ml from Solution #2 Later on, giving you 500 Ml solution)

Add 0.625 Gram MoO3 85.5% (for Solution #2 Only)

Final Results:
Fe 0.1
B 0.014
Mn 0.067
Mo 0.003
Zn 0.014
Cu 0.014
Ca 0.065
