pH is out of balance

Extended periods outside 5.5–6.5 block nutrient uptake — even if you're adding nutrients correctly.

Steps to resolve

  1. Test your water with the pH strip — target 5.5–6.5 (orange to yellow)
  2. Adjust using pH Up or Down as needed
  3. Only add nutrients after pH is corrected
  4. Test weekly going forward to stay in range
