The reservoir needs nutrients. I'm only going to add a gallon at a time, so I don't have to throw out much at harvest.
1 Gallon Added:
E.C.: 2.08
pH: 6.32
Either my timing is off, but OGK seems to be drinking less water. When you look at the Mb meter there is a lot less fluctuation day to day. Whereas, Double Grape is still having large swings in its moisture rate.
