When you only give them water....it's like flushing them.... If you do giv them only water for more than a day or so, watch out for deficiencies....because they depend on every bit of nutrients you give them....

A 1:1:1 ratio is good to start with while they are just rooting.... Once in veg switch it to 3:2:1 grow:micro:bloom....

Yes use the CalMag especially if you are using RO water....

I found out (from someone who's experienced with them cubes) that you don't want to soak them....only wet them.... After you wet them....wait for them to dry out a bit and wet them again.... So be sure not to soak them cubes....and keep an eye on them....
