Hey, I haven't been able to find this searching so sorry if this has been asked a lot... I'm about to top off my hydro setup and my pH is a little high, 6.2. I want to adjust the pH to bring it down to about 5.8 without putting pH down directly into the bubble buckets. Is there a formula to hit my target pH? Oh and it was at 5.8 but it looked like I was getting nutrient burn so I backed the ppm down to 600-700 range for a bit and of course the lower ppm made the pH jump(I read that they share and inversely proportional relationship). I would normally just make my top off water 5.8pH then dump it in but it's usually not that far off of what I want. Will adding only a gallon or two of pH 5.8 top off RO water bring the whole system down to 5.8 or will it just make a small dent in it.
