What does mL/L mean?: Millilitres of nutrient per litre of water. For 10 L of water multiply by 10; pick your tank size and every dose shows its ml underneath.
How many weeks of grow and bloom?: Brands usually print 4 grow weeks and 8 bloom weeks. Adjust them to your plant; an added week repeats the last week's dose.
What is a flush week?: Water only for the last 1–2 weeks before harvest, recommended for aroma and taste. It shows as the 'Flush' column.
How is the shopping list worked out?: For every product, the amount needed over the programme = sum of the doses × tank size × feedings per week. We suggest the smallest bottle that covers it, or a few of the largest size when none does. Change the size and count in the list.
Why may doses differ from the brand chart?: Tap any cell to change its dose. Changed cells are marked and the chart carries a 'Differs from the brand chart' note; when in doubt follow the chart on the label.
