adding nutes lowers PH WHY?
We have an issue with starting a new drip system ... the PH of our tap water is 6.5 ,once the nutients are added we go right off the chart to a whopping 4 ??? We added 2 teaspons of Fox Farm Grow Big to a gallon of tap water (the res holds one gallon)... Please help, what do we need to do to correct this? HELP :)
