CO2 won't help your plants unless you are running over 1000 PPFD, at which point you will need to increase the heat and the nutrients. And I've never seen anyone run CO2 this early. Usually it's run in a flower tent because running 1000 PPFD is way more than vegging plants need to grow well. Just a waste of electricity.I'll be adding more co2 this week.
