let me begin by saying i have put the last few years into the hobby by studying the plant health, nutrients, fish/shrimp health, i have obtained quite impressive results, i will try my best to post them here much as i could, i been busy with life and might not be posting much anymore, so hopefully i could post much as i can today and i promise to post more whenever am free.
I am here to help based on my own research and observation, along with input from our friends who have contributed in this journey. I don’t want full credit, and want to give credit to others as well but anonymously, just for their privacy, unless you feel there is an need for it to be mentioned.
My vision for this thread is that we will post recipes, help others with questions, and discuss opinions. I want everyone to post with full freedom to be honest and blunt, but without personally disrespecting anyone, just as I and some others have been doing in private group chats.
I want to remind everyone that there is no magical recipe that will always work and solve any problem. This thread is simply for people to share what has worked for them, and to share recipes based on scientific data. There will always be some margin of error and room for improvement. But we will start from here, and hopefully I can help some people.
We are not doing this to earn money or run a business. Everything you need regarding recipes and chemicals will be posted here. We just ask for your help and contributions in fostering a positive discussion environment.

Before i post some recipes for our plants, lets start with some testing on fish and shrimps that i did, believe it or not Co2 isn't the solution to everything, it is important but, if your plants are suffering, its not only due to low co2, this is where you are most likely to kill your live stock while plant still struggle to grow. next one is going to sound like what i have mentioned earlier, but higher traces have a negative affect on live stock which is not visible immediately, but it will eventually lead to death to live stock and plants. one good example is Staurogyne repens where it would randomly melt for some people, but there are many other plant Sp. that will do the same under same condition. these were repeated tests over the last few years.
also Use these numbers for reference for later on

Next one is about the above numbers, this would be what plant would use if one have to follow the exact numbers, i have tested it and it does work very well, but it would become almost impossible for one to maintain the above ratio especially if their water parameter aren't stable to begin with, in most cases you will fail with the above numbers due to this reason, any change to these above number results in negative results, for example, raising the B and Zn alone resulted in death to leaves and there was heavy outbreak of BBA, this is why i have always said try not the break the ratio, we can only break it under certain conditions, for example, we can add more of the above numbers if our GH/KH is high to begin with and if there is precipitating/oxidizing event taking place in our tanks, since we cannot successfully use the above numbers i will consider the reasons and we will go from there far as the recipe goes.
next one i want to talk about is many people are confused with what fish really produce, is it NH4 or Urea or something else? the fact is they only Produce NH4, for those who have heavy fish load, they can expect very good plant growth.
next one, which one is superior, chelated or Non chleated recipe? i have used both and i have obtained better growth with Non cheleated, but you will need to add Non cheleated more often vs the cheleated one, i dosed once a week with cheleated one and also had great results. the reason it works better is simply because these metals are now fully free in the water and more available to plants where on the other hand plant have to put much more energy to extract nutrients from the cheleated form.
next one, Fulvic acid, i have used this in some of my mixes, i believe it strongly enhance the existing solution or recipe if you add little bit of it, it will prevent the precipitating and other reaction from happening and it is also helpful to the plants, it kind of act like steroids/booster for the plants. overdosing it will results in GDA, so be careful not to overdose it, i use 0.2-0.5 gram in my solutions.
next one, which source of N is superior for plants? some might argue NO3 is enough, this isn't simply true, i had a chance to try all kind of N sources and NH4 was the most superior one, next one that comes close is Urea, but Urea can sometime fail to work if your water lack nickel enzymes, process of urea degradation was also slow, NH4 can skip certain steps and directly used by plants making it superior to others. Monte carlo was an good example of this test, where it obtained very small leaves when NO3 was the only source of N, soon as NH4 was added, leave size was doubled or tripled.
next one is Potassium, we should never add so much potassium, those who add so much potassium are likely to see pale looking plants and plant don't really use much as what most people has been adding for many years now, plant use almost 3-4x less potassium than NO3, however extra potassium will enhance the plant growth by increasing the uptake of other nutrients.
next one is PO4, this one is tricky one, those who add tons of Po4, are most probably precipitating Iron and other important trace minerals, no need to add so much PO4 in water column, however plant like ludwigia pantanal seems to like little bit extra PO4, so you need to look for the right dose
Next one is Traces/Fe, we will discus as we go, but for now, all i can share is that plant did not use more than 0.1 ppm Fe weekly from DTPA even in high light, rich co2 tank, plant actually had very rich colors, those who are adding tons of Fe from DTPA and still having issue, there issue isn't low Fe, they need to look into other cause such as precipitation and oxidizing. traces also need to stay much lower compare to Ca/Mg and NPK otherwise you will end up with twisted weird growth.
my personal thought based on my own experience: try to stay in ratio whenever you can, breaking the law of ratio will results in buildup of nutrients and also lead toward death to fish/shrimps, plants in the long term, if we cannot keep the ratio and really want to break this law, then make sure we use the protection such as high CEC soil, more water changes, high Ca/Mg NPK to counter this, the only problem with this would be that certain plant will respond in a negative way, while other will not mind at all, long story short, try not to overdose on Micros, its better to dose smaller dose of micro more often than dosing a weekly dose in one single dose. it is best to stock your tank with lots of plants and lots of fish, try not to add so much Bio media or sponge media, good flow is only what you really need, let the fish produce the NH4/PO4 and you only need to add is Traces/Fe/K, no need to add Po4 or No3 in this case, they are not necessary in this case.
Above is based on my own observation and many tests over the many years, they might work for you or not, i cannot promise, but i am quite certain if you did everything right as i have mentioned, you will see good results, now lets get to some of the recipes.

for those who are interested in this recipe, please follow the link above and you can make the recipe based on just traces only and keep the NPK separate or All in one as you wish, dont forget to add 0.25 gram Fulvic acid to each solution. i have explained everything in this linked thread, possibly everything that you need to know. increase 0.5g Ascorbic Acid to 1 gram, 0.2g Potassium Sorbate to 0.4 gram if you are seeing precipitation, usually Fulvic acid will take care of this though.
tank with some of these above recipes:
feel free to use the above recipes, not for sale as i have mentioned earlier and hopefully you will keep it that way as well, i will post more updates in free time, i will be posting more recipe on NPK as well, i have few based on NH4NO3. please remember try to be very accurate with your calculation, otherwise you will get mixed results, accuracy is extremely important

Before i post some recipes for our plants, lets start with some testing on fish and shrimps that i did, believe it or not Co2 isn't the solution to everything, it is important but, if your plants are suffering, its not only due to low co2, this is where you are most likely to kill your live stock while plant still struggle to grow. next one is going to sound like what i have mentioned earlier, but higher traces have a negative affect on live stock which is not visible immediately, but it will eventually lead to death to live stock and plants. one good example is Staurogyne repens where it would randomly melt for some people, but there are many other plant Sp. that will do the same under same condition. these were repeated tests over the last few years.

this one was one of the best recipe i ever used, this one works best when you have heavy stock of fish and all you need to do is add some Ca/Mg/K along with this micro and leaves the rest to fish, works best for softer water.

KHCO3 Recipe, this one works better than K2co3. K2CO3 melted certain plant sp. so i have decided to move forward with KHCO3 which worked like charm.

K 3 ppm
DKH 0.2

for those who are interested in this recipe, please follow the link above and you can make the recipe based on just traces only and keep the NPK separate or All in one as you wish, dont forget to add 0.25 gram Fulvic acid to each solution. i have explained everything in this linked thread, possibly everything that you need to know. increase 0.5g Ascorbic Acid to 1 gram, 0.2g Potassium Sorbate to 0.4 gram if you are seeing precipitation, usually Fulvic acid will take care of this though.
tank with some of these above recipes:
feel free to use the above recipes, not for sale as i have mentioned earlier and hopefully you will keep it that way as well, i will post more updates in free time, i will be posting more recipe on NPK as well, i have few based on NH4NO3. please remember try to be very accurate with your calculation, otherwise you will get mixed results, accuracy is extremely important
