Calcium nitrate and magnesium with ro water

[Hydro30]

Hey. Just did the switch to ro water. I'm currently using blue planets 3 part nutes. Can anyone suggest how much calcium nitrate and magnesium I should add per gallon of ro water? Or what the ppm should be for both?

Thanks

not sure about the nutes but i use ro water also for my mothers(soil)/SOG(hydro).....DEFINITELY make sure the ph is in line...im on the west coast where the water ph bob's up and down more then a hooker's head on a friday night...at least by me...ph runs between 7.4 & 8.9 depending on the day, its weird...
