Thanks for the comments guys. 
Hey Gonzo, the only other thing I add is my regular cal-mag supplement which has a bit of N in it (2.3-0-0). No the voodoo doesn't effect the pH, at least not if you're using their base nutes.
Hope the coco works out for you.

Hello Hansbricks,
Nice start as always, will be pleasure to watch.
1ml/l of Sensi Grow in RO water makes EC 0,6. Did you add anything else this time? Does voodojuice change PH?
I am curious, I have just started my first coco grow.
Good luck!
