Mark representative bags and compare where pins begin, how they develop and where losses occur. Photograph the same locations with a date and scale. When development is uneven, compare casing lot and application, watering, light and local air conditions. Several factors can produce similar visible symptoms, so preserve the observations and seek help with a specific question.
Harvest to the agreed buyer specification and keep grade weights separate. Review each batch using saleable kilograms, rejects, unsold quantity and payment records. If a new casing material is trialled, change it in a small labelled comparison under competent guidance while keeping other practices consistent. An uncontrolled whole-room change cannot show whether the material or another change caused the result.
