If overused, (or not gently rinsed-off with properly ph'd water) the sugars and other crap in the water can clog the pores in the leaves.

Vegging longer in larger pots will (if raised properly) increase yield.

Never used CO2, so no personal insight there. But I'd learn to walk before attempting to run. :jointsmile:
