Advanced Nutrients Sensi Terra Part 1 & 2 Soil Base Nutrient

The Sensi programme, built for soil rather than adapted to it

Sensi Terra is Advanced Nutrients' two-part base for pre-fertilised soils and soilless blends, supplied here as Part 1 and Part 2 together. Part 1 runs at NPK 2.6-1.1-3.1 and carries the plant through vegetative growth into early bloom. Part 2 takes over from the third week of flower at NPK 1.8-1.8-5.1 - nitrogen steps down, potassium climbs by more than half - so the plant stops building leaf and starts filling out. Both parts are rated for hard and soft water and are naturally pH stable, which on most supplies means no pen and no daily correction.

What's Included

• Sensi Terra Part 1 - grow and early bloom, NPK 2.6-1.1-3.1
• Sensi Terra Part 2 - mid to late bloom, NPK 1.8-1.8-5.1

Both parts are supplied together in the size you select.

Key Benefits

• Formulated for soil, not borrowed from hydro - the ratios account for the reserve a pre-fertilised medium already holds
• Nitrogen steps down and potassium climbs - the move from 2.6-1.1-3.1 to 1.8-1.8-5.1 pulls the plant off leafy growth and into flower development
• Works on hard or soft water - one formulation, no separate water-type version to buy
• Naturally pH stable - no adjustment needed on most water supplies
• Clean, low-salt formulation - will not clog drippers or build up in the medium
• Suits hand-watering and AutoPot - works in pots or beds with no controller and no reservoir dosing
• Takes the standard Advanced Nutrients additives - HammerHead, Big Bud and Overdrive all layer on top

Hydroponic feeds poured onto soil

A nutrient designed for an inert medium releases everything at once into soil that is already holding its own reserve. Salts accumulate, pH drifts, and you get poor nutrient uptake and burnt tips at an EC that would be entirely safe in coco. Carrying a vegetative nitrogen weighting deep into flower compounds it, driving excessive stretch and soft leafy growth at the point the plant should be bulking. Sensi Terra is built around what a pre-fertilised soil already supplies, and rebalances toward potassium once nitrogen stops earning its place.

How to Use

• Mixing: add each part to the water separately and stir well between them - never combine the concentrates
• Weeks 1 to 3, vegetative: Part 1 at 3 to 5.5 ml per litre
• Weeks 4 to 6, late veg into early bloom: Part 1 at 5 to 7 ml per litre
• Weeks 7 to 9, mid bloom: Part 2 at 5 to 7 ml per litre, Part 1 stopped
• Weeks 10 and 11, late bloom: Part 2 at 4 to 6 ml per litre
• Week 12: plain water flush, no feed
• pH: no adjustment needed on most supplies - the feed holds its own range
