Zandor,

Thanks for the reply. Unfortunately, I wasn't asking about what pH I should use, or which nutrients uptake at what pH. I asked a very specific question about why my pH rises as much as 0.2 per hour, and what I might be able to do about it.

Your answer, to read the FAQ section regarding proper pH levels, had absolutely nothing to do with my question, which, again, was why does my pH rise so fast and how can I slow it down.


I've seen many questions posted on this forum where your response was to read the FAQ section, and appropriately so, because the particular question asked has already been answered there. Moreover, in many of those responses, you've indicated your frustration that the person who posted the question didn't read the forum user guide carefully enough so that he/she would know to check in the FAQ section first to see if their question is answered before posting. So I'm certain you can understand my frustration that you didn't read my question carefully enough to provide a meaningful response. Could you please do that now. Me and my plants would be extremely grateful.

By the way, thanks to Str8jeepin4pack for the advice. I've raised the base pH level to around 5.8 (not 5.2 like I had been doing).

Green Dreams to all.

I'll set the pH to about 5.3, but within 7 or 8 hours, it will rise to over 7 (around 7.1 or so). I correct the pH by adding granulated citric acid, which takes it back down to the low 5's, but again, in only a few hours, it's risen well above the applicable range (5.2-5.9). I know pH usually drifts up (and this is even beneficial to the plant as it can absorb a Rating: 5
