It is not so much the indoor lights that affect the way plants use nutrients, but rather the light spectrum in the indoor lights. Sunlight contains both a warm and cool spectrum, which is ideal for plants. Typical indoors lights tend to be either warm spectrum or cool spectrum, which means that the full range is not available to indoor plants. A "grow" light will typically have both spectrum.
