Maybe a crazy question but I have to ask. Can I use lemion juice to lower my PH I have heard this may do it organicly, and if so how much to add? One more question while I am hear, I just bought a new meter to read ph and PPM, and not sure how to read the PPM's. My Hanna HI9813-6 gives me a reading of 6.6 ph, 181 ppm, .26 MS and temp of 21.7 c or 70 f. I know on the fertilzer it said to add 2 tsp per gallon so I did , and my PPM should be close, but the meter said 181 ppm what am I reading it wrong HELP!
