1/2 tsp of earth juice down(citric acid) takes my tap ph from 9.0 to 6.5(4 gallons). it is crystal but larger than a powder(that you would see at a store) lots of good info in this thread

I smell some negative reputation coming my way....That being said, If you plan on growing organically and you mix up a proper soil....you can throw your pH meter away.
Check out the Organic Soil Forum...lots of people over there with mucho experience will tell you the same thing....most notably B1 the moderator.
Good luck.

out of those 4 i'd only use citric,
em1 you have to add SO much to really effectively lower pH
i duno if epsom salts will lower pH at all...
if i were to use any kind of vinegar (acetic acid) i'd use horticultural 20 or 30%
citric is a good option
em1 is acidic, but it would be wasteful to use it to lower pH of your water

im using less than an oz a gallon, and the em-1 has to also fight the silica so, id say its really effective at lowering PH
lyfespan, how much are you lowering your pH? one point? 2 points? when i add an oz per gallon to my water it doesn't change the pH more than half a point if that even
em1 is extremely effective tool, just never heard of peeps using it to adjust pH - all the established farmers i've met use horticultural vinegar at 30%
many of these people use em1 as well

my waters ph after adding potassium silicate is around 9.2 in a 50 gallon rez, i dump in 1/2 liter of EM-1 and it drops my ph 6.9
Hello all, I just tested my house well water. I'm looking at using citric acid for my greenhouse. ( free chlorine o%, Ph 8.4 max, Total alkalinity 240 max, Total hardness 0, Cyanuric 100 ). Max is the highest the test strips went to.
I don't understand how the Ph levels go back up in time using citric acid. I will be mixing in a 250 gallon tank. I don't have an injector for mixing. I will mix and test until Ph level is at 6.2 to 6.5 This level will go up when adding nutrients. I only use fish emulsions and Epsom salts for my plants. Nutrients are not added to main storage tank. They are mixed separately at time of feeding for various strain requirements. All breeder recommendations are followed. If someone can tell me why Ph levels go back up using citiric acid. I would like to know why? The only other thing in my soil mix is earthworms. Thanks for your time. Peace

R/O starts at 7.
The addition of a tiny bit of nearly any nutrient or emulsion will drop it quite easily. I personally use a touch of maxibloom as pH down. In between feedings.
Why give your plants the chance to absorb something they'll never turn into awesome product? I use potassium citrate for pH up and have had a quart of pH down for years, with over half left. R/O makes all the difference.
