Growth and bulk productivity yes, for certain species of plant. Nutritional value no. Mineral uptake is impacted after a certain CO2 concentration which is why you need to get the soil right for growing in CO2 enriched greenhouses.
So not so good for feeding large human populations. Expect to pay large amounts of tax to deal with the impact of increased migration due to hunger.
