Low Nitrogen (N) – Give your plant relatively low levels of Nitrogen, especially in the second half of the flowering stage when the plant has stopped growing vegetatively and buds are fattening up. The plant needs a lot of Nitrogen for vegetative growth but doesn’t need nearly as much for making buds. In fact, too much nitrogen in the ripening stage can discourage bud production and hurt your yields.
Plenty of Phosphorus (P) – Phosphorus is incredibly important to flower production and giving plants plenty of Phosphorus in the flowering stage will help increase the total number of flowers
Potassium (K) – Potassium is often overlooked compared to Phosphorus (which is often considered a bud booster) but Potassium may actually be even more important! Providing a good source of Potassium increases the size and density of each individual flower.
