See exactly what nutrients your plants need at each growth stage
Understanding NPK
N-P-K stands for Nitrogen, Phosphorus, and Potassium — the three primary macronutrients cannabis needs. The ratio changes dramatically through the plant's lifecycle: Nitrogen (N) — drives vegetative growth, leaf development Phosphorus (P) — essential for root development and flower formation Potassium (K) — regulates water uptake, enzyme activation, bud density Cal-Mag — calcium and magnesium supplementation, critical in coco and filtered water
Feeding Tips
Always start at half strength and increase gradually Monitor pH — 6.0-6.5 for soil, 5.5-6.0 for coco/hydro Watch for tip burn (nutrient excess) or yellowing (deficiency) Flush with plain water for the last 7-14 days before harvest Less is more — it's easier to fix underfeeding than overfeeding For complete guides: Nutrients Guide | Watering Guide | VPD Chart | Organic Growing
