Common crops affected
- Blueberries
Why it matters
Brix drives flavour, grade, and price; it's built by healthy photosynthesis plus potassium and finishing nutrition, so two blocks of the same variety can differ widely.
When it appears
During fruit development and ripening — the finishing window.
How to identify it
- Low refractometer Brix at harvest
- Bland, flat flavour
- Poor premium-market grading
How to manage it
- Protect late-season leaf health; supply potassium; avoid late nitrogen.
- Apply Brix Boost with Potassium Pro through ripening.
