Hey Hansbricks.. I have a syringe that measures ML's. I got it now. I will def mix my nutes in a gallon jug before entering the rez. I plan to buy gallon jugs of distilled water each week. I will PH after mixing the nutes. Do i make that 4ML mix for every gallon of water I add to the res seperately? And how about the amount of ML's for bud candy, big bud, and voodoo? And what weeks to add those 3 nutes?
