Like most myths mate your hypothesis which leads to conclusion is flawed. Thus (hypothesis = flawed leads to conclusion = flawed) What is happening is that if you fail to provide N at a time when the plant requires N it will yellow or as you call it fade. If you perhaps read some books you'd come to learn how nutrients are transported and used in photosynthesis and carbon petitioning. N particularly is very important in canopy photosynthesis. I.e. Since about half of leaf nitrogen is invested in photosynthetic proteins, there is a strong correlation between the photosynthetic capacity (the light-saturated rate of photosynthesis at an ambient condition) and leaf nitrogen content per unit area (Field and Mooney, 1986; Evans, 1989a). Thus, to have high rates of photosynthesis, canopies should accumulate a large amount of nitrogen in their leaves (Hirose and Werger, 1987b
Basically N is incredibly important in chlorophyll production. Chlorophyll is what gives the plant the green colour. By starving the plant of N it cannot produce chlorophyll = yellowing of the leaves.
N though and indeed chlorophyll are of interest during the flush which I have made pretty clear. Does this mean the plant eats up reserves of nutrient ions... No it doesn't... Not even close.
