Bba is usually caused by inconsistent co2 rather than not enough, though, not enoug can be a cause as well
Plants always uptake nutrients just because they are not photosynthesizing does not mean they are not buidling root structure, or taking store energy to build chlorophyll, or enzymes.
Photosynthesis is the active use of light energy to form carbohydrates as a usuable energy source
