I have seen a grow in high times of WW under a bunch of 1000 watt lights.
What is light bleaching?
Does anyone have a picture of it?

co2 is only worth your time if everything is in check

That comes directly from too much light, too much power so to speak 'burning out' the capacitors (chlorophyll.)
