First time with CO2. How much can I boost my nutes?

[btownbuddah]

I've been told that with the help of CO2 you can safely add more nutes for better yield. Is this true? And if so, how much can I increase my ppm. Do I maintain a higher ppm or just boost it periodically? What signs should I look for that I put too much in? The directions say to increase ppm by 1000 without CO2. Any advice here would be much appreciated. Thanks

Gradually increase your base nutes until you see the first signs of tip scorch. Record the ppm number at that point. Then do a partial res change and bring the ppm to just UNDER that number. Monitor for signs of deficiency or tip burn.

I know you have read alot about co2 but

PLEASE do not use in an living area.or connected to living space.
It's heavier than air and can kill very easy. It fills a room and pushes O2 out..

I only said something because of first time use. You can bring your temp up too for more use of co2 but watch the water temp.

Good luck.
