Increase BioBizz Grow to 2–2.5ml/L for young plants in coco.
Consider switching to a mineral-based coco nutrient (like Canna Coco or Advanced Nutrients Coco) — they’re more immediately available in soilless setups.
Or add microbes/enzymes to help process BioBizz organics in coco.
2. pH Imbalance
Coco needs water/nutrients at 5.8–6.0 pH for optimal uptake.
If pH is above 6.3+, it can cause lockout, even if nutrients are present.
Fix:
Double-check your pH pen and solution.
Stick to a target pH of 5.8–6.0 for coco.
3. Overwatering or poor drainage
Coco needs to dry slightly between waterings, especially early on.
Constant moisture + low oxygen can cause droop + yellowing.
Fix:
Ensure pots drain well.
Let the top inch of coco dry out a bit before watering again
