Maximise your harvest density and unleash heavy commercial yields with Plagron PK 13-14. This pure, professional-grade mineral fertiliser is engineered to deliver a concentrated blast of extra phosphorus and potassium during the critical peak of the flowering phase, resulting in flowers and fruits that are significantly more compact, solid, and heavy.

During mid-to-late bloom, a plant's requirement for secondary macronutrients spikes dramatically. PK 13-14 steps in to satisfy this physiological demand with high-grade, fully bio-available minerals. By forcing rapid cellular swelling and increasing structural tissue density within the fruiting sites, it guarantees an aggressive final weight increase.

Core Cultivation Advantages:

Uncompromising Yield Density: Generates notably firmer, heavier, and tighter floral structures, adding serious bulk and bag-appeal to your final harvest.
Pure Mineral Performance: Formulated with top-tier, clean mineral inputs that dissolve instantly in water, ensuring rapid uptake by the root system with zero residue left behind.
Optimised Phosphorus ( $P$ ) Levels: Phosphorus plays an fundamental role in the plant's internal energy transfer systems ( $ATP$ ), driving heavy flower production and accelerating cellular division.
High-Grade Potassium ( $K$ ) Delivery: Potassium regulates water transport, strengthens plant cell walls, and triggers the heavy sugar and carbohydrate synthesis needed to fill out large fruits.

Application Timing & Dosing

PK 13-14 is an aggressive generative catalyst and should be introduced precisely when flowers are fully formed and entering their swelling stage:

Flowering Week	Recommended Dosage	Application Frequency
Weeks 1 to 3	Do Not Apply	Allow flowers to establish using base nutrients only.
Peak Bloom (Approx. Week 4)	2ml per 1 Litre of water ( $1:500$ )	Apply with every irrigation cycle alongside your base bloom feed.
Final Flush Week	Do Not Apply	Flush the substrate with fresh water to clear remaining mineral salts.

Step-by-Step Usage Instructions:

1.Shake the bottle thoroughly:Agitation.

Before measuring out your dose, shake the PK 13-14 container vigorously to ensure all dense mineral salts are perfectly distributed.

2.Add PK 13-14 to water first:Booster Baseline.

Measure exactly 2ml of PK 13-14 per 1 Litre of fresh water and mix it into your tank. Always add your PK booster to the water before adding your primary base feeds.

3.Top up with base nutrients:Base Balancing.

Slowly add your primary bloom feed (such as Terra Bloom or Hydro Bloom) until you reach your target Electrical Conductivity (EC) level. Stir the reservoir thoroughly for 10 seconds.

4.Verify and adjust pH:Final Check.

Test your final nutrient solution using a digital meter. Calibrate the pH back into your medium's optimum target zone using Plagron Lemon Kick if necessary, then feed your crops.
