ONLY USE HALF OF WHAT ADVANCED SAYS .....I USE REVERSE OSMOSIS WATER FROM WALMART ITS LIKE 40 CENTS A GALLON AND IT HAS 0000000 EC...SO YOU CAN MAKE YOU R EC PERFECT AND TRACK IT DOWN TO THE POINT .01.....
WATER IS CRUCIAL I USED TAP FOR YEARS BUT FIND THE RO WATER MAKES IT EASY TO WORK WITH IN THE FIRST WEEKS WHEN YOUR PLANTS ARE LITTLE AND CAN ONLY TAKE LIKE 400PPM ....
I USE LIKE 3ML OF A AND B SENSI TO 2 GALLONS IN THE START WITH RO Water and some rhino skin and some sensimyne which is like voodoo juice if you not using tea or bennies you need to find out what this is becuase when it comes to hydro the roots are everything if your roots arent bright white your fucking up.....
