When I mix up my nutes it drags my PH down very low (4.5) so I went and bought some PH up to raise it after I mix my nutes... Problem is the instructions say that to get it to the PH level i want I need to add 1 teaspoon of the PH up per.... ONE HUNDRED (100) gallons..................................
I only mix my nutes per the gallon, so does that mean I need to add 1/100th of a teaspoon??? I added like 1/2 teaspoon to my half gallon of nutes left and it raised it all the way up alkaline... What should I do?
