Rawr, I can't search for the phrase "ph up" simply because it's too short, SO I'm coming to you for help.
Apparantly, the water I've been giving my plants is too low causing a nutrient deficiency, so I need something to raise it! (lucky me, I bought a bottle of PH down but not up!)
I've checked the faq as well as tried to search my ass off.
I might have overlooked something, I remember hearing vinegar being used but I can't remember if that would make the soil more alkaline or acidic.
<3 in advance.
