re: RQS Amnesia Haze - 150W/600W HPS - AquaFarm & Soil - GHE
Just retrived my ph meter(was using strips before) and ec meter today. The ph was at 6.5 and the EC meter shown 2140us/cm is that to high? i have readen a little around on google but there is so meny answers some say its to high and some says its perfect?
im from europe so 1EC=1000us/cm = 640ppm Right?
so with a ec on 2140us/cm its giving me a ppm at 1370ppm
this is the chart ive found on a other site
