Sounds like this is the safest and will add flavor to the plants...anyone tell me how much they use per gallon and how far are you dropping the number...like 8 down to 6?
Sorry to bump an old thread, but I have had nothing but problems with ph stability and citric acid, it just seems to break down over night and can't keep up with a standard ph UP product (I use grow more FYI) so my ph ends up closer to 7 rather than 5.8 after 12 hrs... Just my 2cents
I have, over the years, gradually gone away from using pH up and down. I avoid adjusting the pH of my res at all costs. It is just one more little thing that disrupts the harmony of your res. On top of that, your standard pH adjusters are not good for your roots and precipitate useful nutrients out of your solution. Even though minor, it has a negative effect on the integrity of your solution and even worse, adding pH down to your res one day and then up the next day is a not a good thing to do. What I have done, is to make sure I am using nutrients that are properly adjusted by the nutrient company so that when I mix them, the pH is at a good starting point.
What kind of hydro system are you running?
What kind of nutrients are you running?
What is your starting pH on a fresh res with no adjustment?
What is your target pH range?
Most of the alternate pH adjusting methods (citric acid, vinegar, aspirin, etc.) don't hold the pH for very long, just like you are experiencing and you just have to keep pouring more and more stuff into your res, that ideally, you really don't want to.
a pH of 5.8 is better than a ph of 7Sorry to bump an old thread, but I have had nothing but problems with ph stability and citric acid, it just seems to break down over night and can't keep up with a standard ph UP product (I use grow more FYI) so my ph ends up closer to 7 rather than 5.8 after 12 hrs...

it's a better idea to test your water and then add your newts let him sit overnight shake it up real good and test it again and den PHmix a few table spoons in a bottle with water. slowly add that to your rez OR get your rez to around 7 before you add your nutes, i've found it usually falls into range after you've added your nutes. at least with pure blend pro and house and garden. generally as your TDS goes up your Ph goes down.
How do you shake your 100gal rez?it's a better idea to test your water and then add your newts let him sit overnight shake it up real good and test it again and den PH
can you explain? and citric acid should not be used in a res. Soil is a different story.Sounds like everyone should read on the citric acid cycle. If there's any bicarbonates in your rez, then citric acid makes carbonic acid which turns into co2. Carbonates may also be found in your soil as ph buffers. Another tool on the belt If you ask me.
