I was reading Tom's article on non co2 tanks regardiing the production of the rubisco enzyme produced by plants to adapt to low co2. As I understand it, in the prescence of high levels of co2 the plants get "lazy" and produce less rubisco.

I started to think about EI dosing. Assumiing that in a given set of conditions a nitrate level of 15 ppm was just enough would the prescence of more nitrates make it easier for plants to take up nitrates and enhance growth ? What about other nutrients ?
