Understanding NPK ratios for cannabis
N (Nitrogen) = vegetative growth, big green leaves. P (Phosphorus) = root development, flowering. K (Potassium) = overall health, disease resistance.
Veg ratio: 3-1-2 (high N)
Flower ratio: 1-3-2 (high P)
Late flower: 0-3-3 (zero N)

Excellent guide. One thing I'd add: patience is the most important nutrient.

I wish I had this guide when I started. Would have saved me months of trial and error.
