Hi guys, as a new grower my struggle is with my watering pH after dissolving 1g of Calmag in a liter of tap water. My tap gives me a 7.2 pH and 30 ppm, after adding Calmag if bumps to 8.5pH and 124 ppm. Then I start adding drops of pH down solution (chloridric acid) until the pH reaches 6.5... everything looks fine for a few minutes until the pH begins to go up for no apparent reason. Usually it goes all the way up to 8 again, then I add more pH down bringing to 6.5 and it goes up again, etc... can't stabilize at 6.5! By adding that much acid I end up with a very high ppm (I guess the pH down solution adds particles to the water) and still not able to stabilize the watering pH on 6.5, what am I doing wrong here?
Thank you.
Thank you.
