Start by adding a small amount (for example ~1 mL per gallon) of pH Up to your nutrient solution, wait 15‑30 minutes, then retest the pH. Adjust gradually until you reach your desired pH level. Ideal for use when pH drops below target range and you need to raise it reliably. :contentReference[oaicite:2]{index=2}
