Description
Head Masta is a premium bloom-stage additive formulated to maximise the density, weight and terpene profile of flowers during the mid-to-late flowering phase. We have been recommending Head Masta to UK cultivators since 2017 as a highly regarded flower finisher that growers consistently report producing noticeable improvements in bud hardness, resin production and overall harvest weight in the final weeks of bloom.
Targeted Flower Development for Maximum Density and Resin
Head Masta combines a targeted PK profile with natural plant-derived stimulants and amino acid precursors that collectively drive three parallel processes during late flowering: continued cell expansion in developing flowers increases bud size and density; elevated terpene and resin synthesis precursors improve the essential oil content and aromatic profile of the harvest; and the carbohydrate loading fraction supports the energy-intensive metabolic activity required for maximum resin and flower mass accumulation in the final two to three weeks of bloom.
The product is designed to work alongside your existing base nutrient programme without requiring a complete overhaul of your feeding schedule. Applied from week four of flowering through to the start of your flush week, it provides a targeted late-bloom boost that complements rather than replaces the rest of your additive programme. It is compatible with all major nutrient brands and growing media types.
Application, EC and Flush Protocol
Introduce Head Masta from week four of flowering and apply at the manufacturer’s recommended dose alongside your base bloom nutrient. Monitor total EC carefully when stacking additives — reduce base nutrient dose slightly if total EC is approaching your plant’s upper tolerance threshold. Discontinue one week before your planned flush start date and switch to a quality flushing agent to clear mineral reserves before harvest.
Pairs well with silicon supplements during mid-flower to support trichome structural integrity, and with a terpene-focused finisher during the final flush week. A well-regarded UK grow room additive for growers focused on maximising late-stage flower quality and yield.
