My DWC Nutrient Schedule

This is the exact schedule I follow for my DWC grows using the General Hydroponics 3-Part Flora Series and my preferred additives. All measurements are per gallon of water.

I maintain pH at 6.1 throughout veg and 5.8 in flower. I never exceed 5 ml of Orca or Silica per 5 gallons, and I only use Rapid Start during the seedling stage.

Use this as a baseline and adjust if your plants show signs of stress or hunger.

Nutrient Table

Notes:

  • All amounts above are measured per 5 gallons of water.

  • Orca and Silica stay at 5 ml (total) per 5 gallons throughout.

  • Rapid Start is for seedling stage only.

  • pH: 6.1 in veg; 5.8 in flower.

  • Monitor EC/PPM and adjust slightly if needed.
