How about lemon for PH down?

I was wondering what would happen if i used citric acid (lemon juice) to drop the PH a bit?
It is also organic.... Plus lemons got 0.3moles/liter citric acid .
Has anyone tried it ?

yeh i used it, worked fine, also used vinegar

Phiew..... Thanks for responding
I just did it and was a bit scared
I dont want to piss my plant like some ppl do .
Thanks

actually lemon juice works great but doesnt last long from my experince with it

so vinegar works better?

piss is actually good for plant if its watered down, contains lots of nitrogen.

vinegar is basically same its just a short term fix til u can get sum proper stuff, if its a soil grow u doin, then in my experience the acidity in the soil gradually rises til flush, so dnt use to much or ull start locking out nutes.
