Atami ATA Terra Max

The flowering half of Atami's soil base-feed pairing

Atami ATA Terra Max is the bloom-stage counterpart to ATA Terra Leaves, a complete professional flowering formula built specifically for soil growing. It stimulates the start of flowering once a plant is switched over and keeps supporting flower development through to the finish, and like the rest of the Terra range it is directly soluble and fast-acting so nutrients reach the root zone without lag.

Its NPK sits around 2-2-4, giving it a potassium lean that suits the flowering stage while keeping nitrogen low enough to avoid pushing unwanted leafy growth once a plant should be directing energy into buds. Because soil substrate already holds a natural reserve of calcium and other nutrients, Terra Max is formulated with minimal added calcium and a relatively low overall NPK strength compared with hydro-calibrated bloom feeds, reducing the risk of overfertilising a soil-grown plant during flower.

Dosing typically starts light at the beginning of flowering and increases gradually week by week as the plant moves deeper into bloom, giving a ramping feed curve that follows the plant's rising nutrient demand through to the final weeks before flush. Used together, ATA Terra Leaves through veg and ATA Terra Max through flower give soil growers a straightforward, purpose-built two-stage base feed rather than a single all-purpose formula stretched across the whole cycle.

• Directly soluble and fast-acting; nutrients reach the root zone quickly
• Potassium-led NPK around 2-2-4; tuned for flowering without excess nitrogen
• Low added calcium; matched to soil's natural reserve to prevent overfertilising
• Ramping dose through flower; starts light and increases week by week
• Pairs with ATA Terra Leaves; completes Atami's two-part soil base feed system
• Built specifically for soil; not a hydro bloom feed adapted for soil use
