this is why I continue to use NH4/Urea instead of NO3, NH4/Urea is constantly being uptaken by the plants and the aqua soil as it attract + charges and mostly ignore - Charges. some people add Osmocote or Ammonium based root tabs to achieve the same effect.

this part I can agree on that they have different mythology the ratio doesn't have to be the exact, but they are somewhat similar. my point was that if you have 0.3 ppm NH4 in the water, you don't need lot of K to counter the toxicity if that was the case. again, if someone is adding 8-10 ppm K...

then we would expect Tropica to increase their K levels in their liquid fertilizer, on top of that they add more NH4 in their liquid fertilizer while using NH4 rich ADA soil. this is the question only ADA can answer, why they choose to add more K in the water? they too add more NH4/Urea in their...

this is something Marcel has also talked about at some point and some of the the dosing was created based on this hypothesis, where plant were provided nutrients in such manner. the hypothesis was that if there was excess of one nutrient, plant spent too much energy uptaking that nutrient and...

I strongly encourage you or anyone to reach out to him, because this is only going to help the hobby and the hobbyist.

What if your beliefs changes in the next few years? Just like the belief that you cannot have high lights, low to no Co2 or nutrients without getting algae.

We will be exploring all options, including high lights no co2.

have you thought about just trying 0.1 ppm Fe target weekly?? Iron deficiency with 0.5 ppm Fe weekly is just not possible at this point. do a big water change and see if you notice any changes before adding more Fe

@plantnoobdude had the exact same issues. currently you are dosing 0.5 Fe DTPA weekly ? something like this? Fe 0.5 Mn 0.28 B 0.03 Cu 0.04 Mo 0.01 Zn 0.01 :eek:

lol i forgot we were on your thread. now I must be drunk.

one of my biggest worry is when someone is making their own micros and make any kind of small error because we are talking about some numbers in ppb. I hope this is not the case here, am not saying you don't know what you are doing. can you post some recent pictures of your plants?

you gonna have to be little patient and hang in there, we will eventually solve this, its not going to happen overnight. this is based on Tenso Coktail Clone, weather I use the Tropica clone or this one they both have good results as they both use Fe;Mn ratio around 2:1 I believe you use the...

We do not use TDS to guess what dose to add, TDS has nothing to do with it. The only thing TDS will do is that it will rise anytime you add anything in the water. However, the TDS can also fall if your soil is rich in CEC and also a choice of your fertilizer that is low in several elements such...

#1,058 have covered most of the answers already regarding lean. My approach isn't much different except we do not need to add high gh such as 5, this is reasonable if one want to add bit more extra Fe and traces, in some cases people who keep shrimps. My approach is similar to tropica or...

@Regent have you tried adding some DTPA Fe yet?
