Advanced Nutrients PH up, how much do I use?

HOw much should I use per gallon, the label says to use small increments. so whats small 1 tsp or 1/4tsp? anyone have experience with this product? I'm trying to bring up the soil ph from 5.0 to 6.5, thank you.

I think it depends on your solution in your reservoir how much you will need. That comes from experimentation and notes, just add a few drops or ml and see where it takes your solution. If its too much back it down, for my solution I know it takes about 5ml to raise it approx 3 tenths on my meter. From there its just simple addition or subtraction.

Edit: year late lol.. hopefully you figured it out by now.

The PH level is mainly maintained by the water,
Mineral water has the PH level of 7.0,
Better you can try that....
Also rainwater has Nitrogen and other minerals which is rich in PH level...
