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.
stinkyattic Reviewed by stinkyattic on . First time with CO2. How much can I boost my nutes? 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 Rating: 5
