PK 13-14

Top Crop PK 13-14 is a classic phosphorus and potassium bloom booster with a 13-14 PK composition (P2O5 13%, K2O 14%), the same proven formula widely used in Dutch-style cannabis cultivation. It's designed as a supplemental bloom additive for the mid-to-late flowering phase, when cannabis plants have their highest phosphorus and potassium requirements for bud development, resin production, and ripening.

Being nitrogen-free, PK 13-14 adds pure PK load to your existing base nutrient program without disrupting the nitrogen balance. This is critical during mid-to-late flower when excess nitrogen can inhibit flowering and reduce terpene production. Use it progressively in weeks 4-7 of flowering at increasing doses, then flush before harvest.

Compatible with soil, coco, and hydroponic systems. Works as part of Top Crop's Spanish-developed nutrient line or alongside any other base nutrient program. Top Crop is known for clean, effective Spanish cannabis nutrients that follow European cultivation traditions without unnecessary complexity.
