How much lemon juice do you add per gallon to lower ph?.

[Justin stoneberg]

Does anybody have a formula that works in telling how much lemon juice per gallon will lower ph to optimal ranges?...... photo plants love it but the autos are looking rough

I'd just get some citric acid. 1/16 tsp per gal lowers my 7.8 water to 6.8 or so.

.. thank you !. I'd rather try this method versus ph powders.. Do you need to let it sit in the water for any period of time to work or is it a fast process... I've had great success using the well water in the past but that's also been from using sohum live earth versus the strawberry field/ ocean mix I'm using now . The strains I'm growing are either finicky or the wells waters change ph often?.... its guess its time I get a decent meter as well....

I've got well water too. And the citric acid is super cheap. It dissolves pretty fast in hot water. Like a few minutes.

Thanks again.

Experts also estimate that to adjust the pH of a gallon of water, two drops of pure lemon juice can lower pH levels by 0.5. You can add more if needed.
but i would add citric as mentioned above

use citric acid crystals , but do some research on them, as some citric acid products contain suger that can cause bacterial problems further down the line

Thank you sir. I was just looking at what Amazon had to offer ... how much crystal would I use then per gallon .. or is it the same as the lemon juice amount listed above.

 

[go go kid]

1/4 tsp/ GAL and then check, that works on RO water, but everyones water is differant

s this for growing or flowering? as if its for growing plants, citric is ok if you dont have nitric, but duting flowering, phosphoric acid is best as it adds phosphourus to the water and helps wih flowering

Citric acid also fights powdery mildew and bugs. It’s good stuff in your toolbox.

How are you growing? Soil, hydro, coco, peat, etc... Lemon juice might not be a good choice to lower pH.

 

[Kassiopeija]

in soil the citric promoting bacteria's may be a good thing

Use ProMix HP and you won't have to ph

My well water's ppm is ~500, I'm using Mega Crop one part in 3 gallon fabric pots. 600w MH/HPS in a 4 x 4.

Non ph'ed well water @ ~ 7.5, day 72 for auto's from autoflower dot ca.



Purple Silverback @ day 79.



BTW > 6.7g/gallon of Mega Crop was too much, 4.8g seems to be the happy spot !

Gelato @ day 75.



Cheers

They would need your same water source amongst other things to get the same results with what’s working for you.

True but I'd sure give it a try.

I've hauled water, bought water, considered equipment to treat water and ended up just using it as is

BTW > my water is hard, clean toilet bowl has a "ring" within three days !

The point is ProMix HP is buffered and doesn't not require you to ph water in...

And it has No nutrients in it so you have complete control over what food you feed.

I used to add 45 drops of acid/gallon to bring my ph down to 6, don't do that any more....

Cheers

I've been using 2 Smidgens Per 32 oz of water. I get about 6.35 pH that way with lemon juice, but it varies a little based on how much citric acid each lemon has.

So for a gallon it's about 1/3 of a teaspoon.
You'll do better to get a digital pH meter if you have one so you can see each time you mix it with water.

Lemon juice converts pretty quickly and becomes alkaline. Use citric acid like other suggested or even better phosphoric acid to lower pH.
