best organic fertilizer for flowering marijuana plants 1-3-3 Bloom Fertilizer

1-3-3 Bloom – Fuel for Bud Growth & Resin Production

1-3-3 Bloom is a premium liquid fertilizer and biostimulant crafted for the dedicated cultivation of cannabis. Its balanced nutrient profile and rich blend of organic ingredients work synergistically to promote robust bud development, enhance cannabinoid and terpene production, and support overall plant health and vigor.

🧬 Key Benefits

• Improves Nutrient Uptake
  Humic and fulvic compounds increase the bioavailability of nutrients, helping your plants absorb what they need more efficiently while stimulating beneficial microbial activity in the root zone.

• Stimulates Root & Flower Development
  Natural plant hormones from kelp extracts—like cytokinins and auxins—encourage deeper rooting, fuller flowers, and faster nutrient cycling throughout bloom.

• Strengthens Stress Resistance
  A consistent feed with kelp and marine-derived inputs helps plants better withstand environmental stress, drought, pests, and disease during the crucial bloom phase.

• Optimizes Bud Size, Density & Resin Production
  The clean potassium content from sulfate of potash directly supports bud structure, water regulation, and terpene/cannabinoid synthesis—delivering rich aromas and potent yields.

🌿 How to Use

• Shake well before use.

• Mix 5mL (1 tsp) per 1 litre of unchlorinated water.

• Apply every 7 days throughout flowering, beginning at bud set and continuing through peak bloom.
