I have been running CO2 into my 20 gallon high tank for about two weeks now. My bubble checker says that I have good CO2 levels for plant growth.
I run 48 watts of T5 light into the tank.

These plants are tied to driftwood.

Since introducing CO2 I have noticed yellowing and deterioration of some of the leaves on these plants. They were gorgeous before adding CO2.

Could CO2 be hurting these plants?

Thank you.

Co2 is not the problem. The problem is a lack of nutrients. Dose more, because your plants are using more now that you have co2.

yup, plus adding co2 has increased growth, which in turn increases the demand for nutrients

Agreed. I had anubias before and after co2 introduction. They took off afterwards.
