Look, I get we are all playing god with twigs in cups, but some of you are dropping three figures on 'specialized' organic pH down when basic white vinegar does the exact same thing. Stop letting these liquid-fertilizer bros charge you premium-unleaded prices for what is essentially glorified pond water and food coloring. My mini willow is literally sitting in a bucket of diluted cheap lawn food and a dash of vinegar and it is thriving. You do not need a digital lab-grade spectrometer to grow a stick in water, you absolute clowns.
