Co2 confusion

I talked to a guy who said co2 was more benifecial during veg. I am using co2 during flower. I think I see an inncrease in flower size! My question is at what point during flower should I turn off the co2? run all the way untill the finish of my 8 week cycle? My plants seem to be developing ( mostly white pistols) even at week seven! If I turn it off will thye finish faster? Thanks

Keep it flowing. Gas gas gas no brakes lol.

dont stop now, co2 is good for all plants all the time. most guys use it for flower only to save some cash. i use it on all phases including a little blowing in my clone box.
