Well, do not get too exicted, we are already pushing growth at 10-20X the normal rates.

There's only so much, so fast a plant can metabolically grow before time factors into limiting the rates.

At 30ppm dissoloved CO2, you are near maxmimal rates, so adding this might get another 20% more growth, not 10,000X more.

It takes time for the plant to organize all these components into tisuue.
Lots of very complex parts need assembled.
The plants are quite fast and good at it, but they do have limits.

If you drive some parts too fast and the plant can regulate or down regulate things or upregulate, etc..then you run into trouble.

When you try and maintain high light + high CO2 + non limiting nutrients, things can and do get away from you.

So reduce the ligh and that reduces the speed of growth and the energy added at the root core of plant growth: photosynthesis.

Same with algae.

So less intense growth is easily manged and a very stable way using light.

More than any other single parameter, light tends to be our most easily controlled and stable tool we have.

CO2 is about the most unstable.

So...........

More light= more CO2 related issues and less stablility and resiliency etc.

We do not even have to get to/discuss nutrients to see this issue occurring.
