CO2 Quesions....

I have been introducing CO2 for the past few rotations and like the benefits, but have not got it quite dialed in yet...

I have read elsewhere that you should not give CO2 everyday for the entire Bloom Cycle as it makes the plants "lazy". I read they should get boosts???

I currently have a computer that measures PPM of CO2, and I had it set at 1000, and left it for the entire flowering cycle. I noticed some yellowing toward the end, that I was blaming on the CO2??

I wold like a little feedback on how the CO2 users are doing it.... full tilt? how many ppm's? week on week off? etc..

Thanks for any help!
