soo i'm 4 3/4 weeks into veg.
a question about Cal/Mag and ppm
my ppm's are at like 50 with R/O water.
my question is this..when do i add the cal mag,and take a ppm reading.
the Cal/Mag raises the ppm's quite a bit.
i just dont know when to get a proper reading for the plant's needs...anyway here are some pics.
