Description

Step 3 · Flowering stage

Dense buds. Big terpenes.

When plants start to flower their needs change: after a short growth spurt on stored nitrogen, they need more phosphorus and potassium to fuel flower growth.

Bloom delivers that ratio, enhanced with calcium and magnesium — two common deficiencies that help bud size and terpene production. No more mixing A and B liquids.
