In order for a plant to grow it needs to make new cells and in each cell is DNA. The 4 primary DNA molecules contain Carbon, nitrogen, hydrogen, and oxygen. Chloropyhyll the primary food generating pigment in plants is also made with these same atoms. Without hydrogen you would not have DNA and without DNA you don't have life. Hydrogen and oxygen are absolutely required for growth and that means they are nutrients.

So we add Hydrogen into my list and I have 17, cool
None of this helps anybody on here because nobody can determine whether they have an excess or deficiency in any of these elements.
So the whole project is basically a waste of time, and I'm going to concentrate on stuff I can do to make my plants grow.

Interesting... What is your usual nitrates level ?
Because I have my tanks so heavily planted, nitrates stay at basically zero. Everything I put into the tank has to go through a fish, I am very careful not to over feed, with all the plant virtually every fish will spend some time grazing or scavenging for food. My tanks are slightly acidic which means that I never get an Ammonia spike of any type.
How long does it take them to eat everything ? 2-3 min. ?
So your plants consume all nitrates.
Yep no more than two minutes. What I tell people about how much to feed a fish. Look at the Black part of your fishes eye, that fish will eat what you can put on that per day. No more than that.
When I kept S/W fish along time ago, I met a very experienced fish keeper who told me the same thing.
cytosine
At one time I have zero nitrates and then discovered I have high phosphate levels. Phosphates stayed high until I increansed my nitrate level. A nitrogen deficiency reduces the consumption of all nutrients and that can result in multiple nutrients being at excess levels. Since posphate is is a macro nutrient and one of the easier nutrients ti detect it is often the first problem people find. It doesn't take much nitrate to reduce the excess phosphate and other nutrients in the water. if it is above zero (5ppm would be fine) you know you have enough nitrogen in the water.
Sound a little weird to me as Redfield ratio mentions ten times less phosphate than nitrate, being 1 to 10
