my water is pretty hard here in the socal the PH was at 8 and i'm having a hard time getting it to stay at or around 5.5, I usually have to add PH down after a feed to balance it out again for the next feed. I'm not using any nutriemts yet wanted them to be healthy first. it's been about 2 weeks since I transfferd them to the big pots. I bought a ec/tds meter and out of the package and into the res it read 16, I have no idea what that means.. i'm not sure if i need to calibrate it or how to read it. Please help me understand how to use my meter or what i'm failin at here.
