Description
The trace elements a heavy feed quietly runs short of
Terra Aquatica Oligo Spectrum is a chelated trace element supplement - iron, manganese, zinc, boron, copper and molybdenum. Micronutrients are needed in tiny amounts, which is exactly why they are easy to run short of: a heavy PK addition or a pH excursion can lock them out without the EC meter noticing.
Key Benefits
- Full chelated micronutrient set - stays available across a wider pH band than a raw mineral salt
- Corrects lock-out after a heavy PK - the usual cause of mid-flower iron deficiency
- Very low dose - a small addition per litre, so it barely moves EC
- Root or foliar - a foliar mist fixes an iron shortage faster than a drench
- Works with any base feed - mineral or organic, TriPart, DualPart or otherwise
Yellowing new leaves when the EC reads perfectly
Pale new growth with green veins, in the middle of flower, with a correct EC and a healthy root zone, is almost always locked-out iron or manganese rather than a shortage of feed. Adding more base nutrient makes it worse. A trace element supplement addresses the actual gap and restores nutrient uptake without raising the reservoir strength.
How to Use
- Routine insurance: 0.25 ml per litre weekly through flowering
- Visible deficiency: 0.5 ml per litre for two feeds, then back to the routine rate
- Foliar: 0.5 ml per litre, lights off, on affected leaves
- After a heavy PK: add at the next feed rather than waiting for symptoms
- Note: check pH first - trace lock-out is often a pH problem wearing a deficiency costume
