The answer depends a lot on what plants you are referring to. Anubias and ferns are going to react differently from how HC and most reddish plants react. Once you settle on a light intensity you...

It isn't unusual for an anubias leaf to turn yellow like that soon after you plant it. Just remove the leaf, and wait for the plant to wake up and decide to grow another leaf. They do grow slowly.

How much does the CO2 concentration vary from one area of the tank to another? Is it lower at the water surface or at the bottom? How does surface ripple change this?
