GMax...here is shortcut to Advanced nutrient calculator...just change value and US/Metric...I usually change it to US...In your case 55 gallons, then back to metric and use that to add nutrients to res...I find it easier to measure/mix using metric values...hope this helps

By the way...you are using my recipe; So, I will advise you this...Use all values for light feeding...
Get value for Liquid Karma from B-52 or just use 10ml per gallon

for Calmag...use directions on bottle...10-12ml per gallon

Hygrozyme...use 2/3 of value for sensizyme...or direction's on bottle...10-15ml per gallon.

the calculator will also show you when to quit using voodoo juice...
when to add the 1 week of bud blood...when to stop big bud and use overdrive and flushing agent...these last 4 are used consecutively/never together...
I will try and watch out for you...if you need some help, holler.lw:smokin:
