Feed Smarter. Grow Bigger. Reap the Rewards.
If you’ve ever asked yourself, “Am I feeding too much… or not enough?”—you’re not alone.
Getting your nutrient schedule dialed in is one of the biggest keys to unlocking your plant’s full potential. Too little, and your plants will stall. Too much, and you risk burn, stunted growth, or worse.
That’s why we’ve built The Ultimate Nutrient Schedule—a tested and tracked plan designed to take your plants from seed to harvest with confidence.
🌱 Why You Need a Nutrient Schedule
Think of nutrients like fuel. You wouldn’t give a toddler the diet of a bodybuilder—and cannabis is no different. Different stages of growth require different types and amounts of nutrients.
A proper feeding schedule:
- Prevents over/underfeeding
- Optimizes yield and flavor
- Keeps plants healthy and stress-free
- Works hand-in-hand with your strain’s genetics
📊 The Four Growth Stages & What They Need
1. Seedling Stage (Week 1–2)
🧪 Feeding: Minimal
💧 EC: 0.4–0.6 | pH: 5.8–6.2
✅ Use only root stimulators or diluted seedling formulas
2. Vegetative Stage (Week 3–5)
🌿 Feeding: High nitrogen (N), moderate phosphorus (P), low potassium (K)
💧 EC: 0.8–1.2 | pH: 5.8–6.5
✅ Add CalMag + root boosters + microbial life
3. Early Flowering (Week 6–8)
🌸 Feeding: Moderate nitrogen, high phosphorus and potassium
💧 EC: 1.2–1.6 | pH: 6.0–6.3
✅ Begin bloom boosters + PK additives
4. Late Flower / Ripening (Week 9–10+)
🔥 Feeding: Low nitrogen, high P and K, no additives last week
💧 EC: 1.4–1.8 > FLUSH: EC 0–0.4 | pH: 6.2
✅ Flush for final 7–10 days to enhance taste and burn quality
🧪 Nutrient Schedule Snapshot
(Averages per 10L water)
| Stage | Base Nutrients | CalMag | PK Boosters | EC Target |
|---|---|---|---|---|
| Seedling | ¼ dose | No | No | 0.4–0.6 |
| Vegetative | Full dose Grow | Yes | No | 0.8–1.2 |
| Early Flower | Full Bloom | Yes | Begin | 1.2–1.6 |
| Late Flower | Bloom + PK Max | Optional | Yes | 1.4–1.8 |
| Flush | Water only | No | No | <0.4 |
💡 Always adjust pH to your medium: Soil (6.2–6.8), Coco/Hydro (5.8–6.3)
🧬 Tested with Original Sensible Genetics
We’ve trialled this exact schedule with top-performing strains like:
- 🌱 Black Orchid Auto – Compact and nutrient-sensitive. Responds well to 80% max strength.
- 🦍 Bruce Banner #3 Fast – Hungry for CalMag and bloom boosters in mid-flower.
- 🍬 Purple Ghost Candy – Loves PK in late flower. Watch her stack those trichomes.
Each strain has its own needs, but this schedule is your baseline blueprint—and it works.
📈 Tracking = Mastery
Use a grow journal or app to:
- Log EC and pH each feed
- Track changes in growth, color, and yield
- Adjust based on what you see, not just what’s on paper
Over time, you’ll build a custom feeding profile for your tent, strains, and environment.
💪 Final Word: Feed with Confidence
Feeding doesn’t have to be a guessing game. With this Ultimate Nutrient Schedule, you’ve got a tested framework, proven across dozens of strains, that helps you grow healthier, happier plants from start to finish.
