A practical three-stage starting point.
Seedling / transplant
Use Seed Start Liquid or WSG Root Complete only at crop-validated rates.
Vegetative growth
Position WSG Core or K18 in split fertigation doses.
Correction / stress
Use WSG-Fe, WSG-Mix or Root/Stress Liquid after diagnosis and compatibility review.
BEFORE APPLICATION
Measure first. Dose second.
- Confirm filter and emitter compatibility
- Do not treat humic inputs as a replacement for complete nutrition
- Monitor solution EC and pH after tank preparation
