Ok so I have several questions, this is the meter I have HM TDS EZ Water Quality Tester I want to know what steps I can take to dial in the most efficient quantities of fertilizer. I have read alot about the ec meter but I am having issues because im not sure what conversion to use for my meter or even the guide lines for maximum amount. The fert im testing is Expert Gardener Bloom burst. I have read http://forum.grasscity.com/advanced-growing-techniques/330991-fertilizing-wisely.html but "0,8 EC" means nothing on my meter.
