Over-fertilization

Too many nutrients is worse than too few — it locks out uptake entirely.

Steps to resolve

  1. Drain the tank immediately
  2. Refill with plain cool water — no nutrients
  3. Wait 3 full days before reintroducing nutrients
  4. Always measure: 4 TBSP each Part A & B per gallon (Farmstand) or 6tsp of each part (NooK) on the initial dose, then follow the weekly perscription afterward
