I just transplanted from soil to hydro. My plants are showing little yellow dots on them. I go to check the pH, its 7.8 . So I went and bought some pH Down for pools, picked up some pH up while I was at it. The bottle shows you use 6 oz per 10,000 gallons. When I did the math, using my 20 gal rubbermaid container, it came out to .06 tsp of the stuff. So I put in about 20 grains of the pH down. I know some of you have experience with this. Did I add the proper amount? How much should I add to bring the pH down to optimal levels?
NOTE: I am using the GH3
