Can cannabis plants bounce back from co2 poison?

So My room venting fan timer didn’t kick on and I had 1500 ppm co2 in my room almost all day with no air exchange. Tops started wilting and leaves thinned. Only took 5 hours. My question is will my plants bounce back from this and how long will it take? Thanks in advance

No just put the co2 generator in this morning. Idk stale air meaning it hadn’t been replaced with fresh air. When you run CO2 in a sealed room you’re supposed to vent the air periodically throughout the day to prevent CO2 poisoning. My question is will they bounce back after having that happened.

Pretty sure you need you need to cut back on your co2 ppm and introduce your plants to co2 not just blast them with 1500 off the bat.
Talk about how old are the plants and what stage.
