30% not 80%
I think the law has changed on these acids. I'm sure this used to be much stronger, I'm using 3x as much with this new bottles that's labelled as 30%. Another reviewer thought it was meant to be 80% too. I'll switch to BioBizz organic ph down from now on, same strength and price but healthier for plants and doesn't increase EC.
