Yes that's correct. PK 13-14 is transparent.

Yes, you should regulate the pH and EC value when growing with PK13-14. In mineral fertilizers, the pH value determines the absorption of nutrients by the plant. However, tap water may differ in pH and EC values per region. We recommend a nutrient solution with a pH value between 5.5 and 6.5. You can adjust this pH value with pH Plus, pH Min or Lemon Kick. The correct EC value differs for each plant species and its grow or flowering phase.
