Is it ok to use lemon juice as ph down?

[StillHigh1982]

Is lemon juice good to use to lower my ph for watering or should I just buy a damn bottle of ph down. I'm growing in soil.

A bottle of pH down is not expensive and will last a long time. Less than half a teaspoon will knock a gallon of 7.5pH down to 6.5pH. Just a WAG but I'd bet a quart will grow at least 30 plants or so if your starting water is around 7.5. Unless you have really high pH water or are growing a bunch of plants, one quart will likely last a couple of years.

I use about a teaspoon to water this whole tent at the moment, taking 7.5 down to 6.5. I could knock down my 7.5 tap water and water them at this stage at least 175 times with 1 quart of pH down.

used juice when i first started growing, and it worked. sorta kinda. ph down probaly way better for accuracy .

My city water has a ph of 8.2. I use 1/8th tsp./gal to lower and stabilize at 6.4. I'll have enough left to pass on to the grand kids.

I’ve used earth juice and lemon juice...both worked to go from 8.4 to 6.5

That's what I thought, thanks everyone.

Haha...that stuff goes a long way. Have a nearly full bottle and used it at every watering for months

Keep an eye on the PH, when I used acids such as this for PH down it was very short lived and the PH was right back up above 8. I used sulfur for long term control in soil.
