Maybe I'm giving you the wrong calculation......how about 1500 PPM....that's the conversion from my meter at .5. I brought it up today to 3000 with a fresh change of water and nutes. I'm pretty sure I read somewhere that in the last month I need to be around 1500PPM which comes out to 3000 on my meter ....or using a .5 conversion, 1500 PPM.
