Base B

TPS Base B is the second component of True Plant Science's two-part base nutrient system. With an NPK of 2.5-4.2-1.8, it's phosphorus-forward and provides the complementary mineral profile to Base A's 1.6-3.0-6.8 formulation. Together, A+B deliver complete, balanced cannabis nutrition in a clean, organic-enhanced liquid formula.

What distinguishes TPS Base from simpler two-part systems is the inclusion of two different forms of organic fulvic acid alongside the mineral nutrition — a feature that improves chelation, nutrient uptake efficiency, and root zone biology. The fulvic acids enhance the bioavailability of all other nutrients in the solution.

TPS Base B is used throughout both vegetative and flowering phases, with ratios adjusted as plants progress through their cycle. Mix equal amounts of A and B initially, then adjust the B proportion higher during flowering to increase phosphorus and potassium relative to nitrogen.
