WHAT? No no no. The reason you don't run co2 during the last 2 weeks is because of the Ethylene the plant produces to ripen your flowers. Ethylene is a hydrocarbon gas that plants produce at the end of there life cycle to ripen. If you run high levels of co2 while the plant produces Ethylene c2H4 it effects the hydrocarbon compounds. Ethylene has 2 carbon atoms and 4 hydrogen atoms which work together to ripen. This process is undergoing 4 types of reactions - oxidation, polymerization, halogenation, and hydration which is how you buds get that ripen look and oils.
You never want to affect the Ethylene ripening process, literally 2 gases in high concentrations effect each other. Co2 goes up, Ethylene stays down, Ethylene goes up, Co2 goes down, never ever up at the same time. No different than you guys putting a boveda 62% humidity pack in the jar during the sweating process, u never ever do that. You burp the jar until the jar consistently stays at 56-60% then after its stable a few days later u add the boveda pack so it's not affecting the sweating process. If you run extra co2 while the plant is producing Ethylene c2h4 your plant will literally not ripen correctly and you will have decreased quality, decreased oils, terpenes and everything. Don't do it.
I hope this helps.
