DO you have Yahoo IM?......

You are right, 10ml of PBPG should be twice that if 5ml of PBPG.... Your meter might be off by 10-20ppms but that is normal.... After all, pouring exactly 5ml and 10ml is pretty hard....so if your ppms are within 15-30ppm of double then I would say you are ok.... I have yet to get an exact reading every single time....but I'm always within 30ppms....

Example: Earlier you stated that 5ml of PBPG = 590-600ppm per gal.... So if your meter reads somewhere between 1170-1230, you are still ok....

In a bit I'll be able to run a ppm test to see how far off my ppms are after checking....

I agree, IM would be faster but more people will benefit from being able to read this here....

@PurpleDaddy - Once you see/know how manipulating the levels of what Macro and Micro nutes does, their is no going back to the water and wait game....at least that is how I feel about it....plus, it takes a lot of discipline to measure out nutes this way day in and day out....
