@Thekreeator, I do soil, so I'm not sure how much to use in DWC, but my measurement is 4ml/gal of CaMg+. I think it is a hydro supplement, so that measurement is pretty universal. All in all it depends on the nute. Also, I'd probably keep the temps around 75-77degF, and the water should be cooler than that. Plants have a hard time above 75degF unless you are adding CO2 to your grow room.
