CO2 is missing and from every other table, chart, image etc.
CO2 is a nutrient in the terms of submersed aquatic plants since we enrich it often times.
In agriculture, terrestrial plant, there is no CO2 limitation because the rate of diffusion in air 10,000 times faster than in water.
All those tables, images, examples are exclusively from terrestrial systems, and most do not apply since the levels are extremely high. It could be K+, but it could be CO2.
Plants will take old tissue and use it for new growth in aquatic plants more so than terrestrial species. Keeps algae off, closer to the light and surface(where there is much more CO2 available).
