• Improved flower formation and seed production.
• Earlier and more uniform crop maturity.
• Improvements in crop quality.
• Along with phosphate, potash is instrumental in starch and carbohydrate synthesis, which is essential in the development of large and healthy photosynthesis organs.
• A potash deficiency may lead to reduced cell wall strength, which can lead to the breaking of stems, leafs, and susceptibility to the toppling over and breaking of heavy branches.
• Phosphate deficient plants take longer to initiate flowering, produce fewer flowers, and are restricted in flower size.
• Phosphate deficiencies can result in a reduction in leaf expansion and also the number of leafs.

Use from weeks 3 to 6 at 1ml per L over the peak flower period.
