Quick Answer

HY-GEN PK TOP UP is a concentrated flowering and fruiting additive that supplies soluble phosphorus, potassium and chelated trace elements. It is intended for growers using soil, foliar programs, run-to-waste or recirculating systems once flowers begin to form. TG Hydroponics offers 1L, 5L and 20L variants.

Product Description

HY-GEN PK TOP UP supplements a complete base nutrient program during flowering and fruit development. Its phosphorus and potassium content is paired with chelated manganese, copper and zinc plus boron and molybdenum. Use it as a stage-specific additive rather than as a complete standalone nutrient.

The liquid is suitable for soil applications and hydroponic programs, including run-to-waste and recirculating systems. HY-GEN also identifies foliar use. Always follow the current product label or HY-GEN feed schedule for the crop, growth stage and application method.
