Coco growers chase one thing: rapid veg and heavyweight blooms—without salt lockouts or flavour loss. Bio Diesel® delivers exactly that. Its plant-ready chelates, fulvic acids and microbe-friendly organics keep pH stable, build canopy mass and turbo-charge terpene output, all while slashing the heavy-metal baggage typical of salt-heavy lines. Ready to level-up? Let’s map the four pillars, the current Bio Diesel coco feed schedule and the practical tactics that help you get the most from the program.

Why Choose Bio Diesel for Coco?
- Plant-ready chelates for lightning-fast nutrient uptake.
- Microbe-friendly organics that boost rhizosphere activity.
- pH stability from clone to flush—no daily firefighting.
- Australian-formulated & coco-tested for hard or soft water setups.
- Transparent feed chart validated on commercial farms.
The Four-Pillar Feeding System
1. Base Nutrition — Green Diamond A & B
Every macro and micro element plus fulvic/humic acids and B-vitamins in a clean two-part. Use the coco feed schedule below for stage-specific Green Diamond A & B rates and EC targets.
2. Growth Accelerators
- Supernatural: Cold-processed sea algae sparks explosive root growth.
- Aloevate: Whole-leaf aloe + yucca chelates minerals and thickens cell walls.
- Marine CaMg+: Sea-derived Ca, Mg, N & boron fine-tune N levels.
- Bio One: Live microbes that expand the rhizosphere.
3. Bloom Amplifiers
- Bio Diesel Bloom: Organic fossil-guano booster used throughout the bloom program. Follow the coco feed schedule below for exact weekly rates.
- Rhino K: 15 % potassium citrate for early and late-flower density.
- Rhino PK (Powder): Tank-stable PK shot plus aminos & carbs. Follow the coco feed schedule below for exact weekly rates. Never mix with Rhino K.
4. Maintenance & Finish — Crystal Clear
Flushes bonded salts and supports the maintenance and finishing stages of the program. Saves water versus three-times-pot-volume flushes and spikes terpene expression. Follow the coco feed schedule below for the exact application rate and timing.
Coco Feed Schedule
| Stage | Week | GD A+B (ml/L) | Supernatural | AloeVate | Marine CaMg+ | Bio One | Bio Diesel | Rhino K / PK | EC | pH |
|---|---|---|---|---|---|---|---|---|---|---|
| Propagation | 1-3 | 1 | 0.5 | 2 | – | – | – | – | 1.0 | 6.0 |
| Veg | 1 | 2 | 0.5 | 2 | 0.25 | 1 | – | – | 1.2 | 5.8-6.2 |
| 2 | 2 | 0.5 | 2 | 0.25 | 1 | – | – | 1.2 | 5.8-6.2 | |
| 3 | 3 | 0.5 | 5 | 0.5 | 1 | – | – | 1.8 | 5.8-6.2 | |
| 4-5 | 3 | 1 | 5 | 1.0 | 1 | – | – | 2.2 | 5.8-6.2 | |
| Bloom | 1-3 | 3 | 1 | 5 | – | 1 | 2 | 1 ml K | 1.8-2.0 | 5.8-6.2 |
| 4 | 4 | 1 | 5 | – | 1 | 4 | 1 ml K | 2.1 | 5.8-6.2 | |
| 5-6 | 3 | 1 | 5 | – | 1 | 4 | 1 g PK | 2.2-2.4 | 6.0-6.2 | |
| 7 | 3 | – | T | – | 1 | 4 | 2 g PK | 2.4-2.6 | 6.0-6.2 | |
| Flush | 8-9 | Water | – | T | – | E | R | – | – | – |
Key: T = taper off; E = end; R = Crystal Clear refresh. Choose Rhino K or Rhino PK—never both.

Pro Tips to Max Out Yields
- Mix order matters: Part A → Part B → additives to prevent foaming & lock-out.
- Watch for nutrient drift: Use the feed chart as the baseline for EC and pH rather than treating a single reading in isolation. If readings consistently move away from the chart targets, investigate the cause before increasing nutrient strength.
- CO2 boost: Running supplemental CO2 can change nutrient demand. Use the standard feed-chart EC as your baseline and only increase nutrient strength where environmental conditions and plant response justify it.
-
Smart foliar timing: Apply Supernatural/Aloevate foliar sprays under low light. See the FAQ below for application frequency and when foliar spraying should stop.
Common Mistakes & Fast Fixes
- Over-EC: Leaf tips burn ➜ dilute tank to target EC and run 20 % runoff.
- pH drift: Stalled growth ➜ calibrate meters, adjust with potassium silicate (up) or phosphoric acid (down).
- Additive clashes: Frothing, cloudiness or precipitation in the tank ➜ stop adding products, check the mixing order in the Pro Tips section and confirm that no incompatible additives have been combined before remixing.
- Shallow dry-backs: Mushy roots ➜ allow coco to reach ~30 % moisture before next feed.
FAQ
Can I run Bio Diesel in recirculating systems?
Yes—keep a chiller at 20 °C, swap tanks weekly and use Bio Clear peroxide between cycles to prevent bio-film buildup.
When do I stop Rhino K or Rhino PK?
Cease all PK additives two weeks before final flush to let flavours lock in.
Is Green Diamond safe for seedlings?
Absolutely—start at 1 ml/L and 1.0 EC, then ramp as roots develop.
How often should I foliar spray?
Twice weekly during veg under low light; discontinue after week 3 of bloom.
Can I combine Bio One with other microbe products?
Yes, but space applications 48 hours apart to avoid microbial competition.
What’s the best pH range for coco with Bio Diesel?
Hold 5.8-6.2 throughout; slight rise to 6.0-6.2 in late bloom is fine.
Conclusion
Follow the four pillars, stick to the schedule and practice the pro tips above, and your coco grow will sprint from clone to colossus—delivering dense, resin-rich flowers without endless flushes or deficiency chases.
