A concentrated PK booster for dense, heavy late-stage flowersAtami Bloombastic is a highly concentrated bloom stimulator - Atami's 'Bling-Bling' for your plants - built from high-NPK bio-stimulants and bio-minerals to push explosive, dense flowers and fruit in the final weeks of bloom. Used correctly it adds weight and density while boosting essential oils, taste and smell. It suits most substrates and systems and won't clog feed lines. Loose, underweight flowers late in bloom often mean insufficient PK support, but stacking several PK products together is a classic cause of nutrient burn - Bloombastic is formulated to run on its own for a concentrated finish without over-fertilising.Key Benefits Highly concentrated PK booster - designed to be used sparingly alongside your normal base feed. Denser flowers and fruit - adds weight and density, not just size. Better finishing quality - increases essential oils, taste and aroma. Broadly compatible - works across soil, coco and hydroponic systems without clogging feed lines. Avoiding nutrient burn when stacking flowering boostersRunning multiple PK boosters together is a common cause of nutrient burn from over-fertilisation. Bloombastic is built to be used on its own rather than with other PK products, delivering a concentrated late-flower boost without tipping the plant into excess.How to Use Application window: the last 4-6 weeks of the flowering cycle, through to the final week on plain water. Dosage: 0.5ml per litre - use sparingly. Important: do not combine with other PK boosters, as this risks over-fertilisation and nute burn. Technical Specifications NPK: PK 14-15, as stated by Atami Type: concentrated bloom/PK stimulator (bio-stimulant and bio-mineral) Dosage: 0.5ml per litre Use stage: final 4-6 weeks of flower until the final week on plain water Compatibility: most substrates and systems; do not use with other PK boosters Feed Chart Atami Bloombastic · soil, coco and hydroponics Stage Per 1 L Per 10 L Last 4 to 6 weeks of flowering, through to the final week on plain water 0.5 ml 5 ml Note — Do NOT combine Bloombastic with another PK product — Atami call that "not only unnecessary but potentially risky, due to the chance of over fertilising". It is PK 14-15 and raises EC noticeably. Atami's own grow guide quotes a range of 0.5–1 ml per litre; the conservative 0.5 ml figure is used here. Check pH and EC after mixing.
