Description
Description
Current Culture Bloom A and B is a 2-part premium hydroponics bloom nutrient and hydroponic plant nutrient designed to support the reproductive stage. This two-part base fertilizer is built for growers who want a focused bloom formula that keeps nutrition complete and consistent as plants transition into reproduction.

Cultured Solutions Bloom A and Bloom B are each a full spectrum, mineral based nutrient designed to supply the elements plants need as they push forward into the reproductive stage. The formula is built around a properly balanced dose of minerals in solution, supporting steady performance when flowering and fruiting demand increases. Instead of leaning on heavy extras, this approach keeps the focus on a clean, mineral-based foundation that helps plants thrive during bloom.

Because it’s an A/B bloom formula, you get the control of a two-part nutrient while keeping the overall role simple: deliver complete mineral nutrition for reproductive-stage growth. That makes it a practical fit for growers who value repeatability, want a straightforward bloom nutrient core, and prefer a mineral based nutrient profile with trace minerals rather than a complex additive stack.

Here’s the compact facts layer. Bloom A is a liquid fertilizer with an NPK of 3.7–0–3, and Bloom B is a liquid fertilizer with an NPK of 0.9–4.8–6.2. The mineral inputs include ammonium calcium nitrate and potassium nitrate, plus EDTA-based micronutrient sources and trace borate and molybdate sources; Bloom B is built from potassium phosphate, potassium nitrate, and magnesium sulfate.

This 2-part premium hydroponics bloom nutrient is suitable for rockwool, coco, and soilless media, and it’s also suitable for common hydroponic system styles including deep water culture, recirculating deep water culture, nutrient film technique, and aeroponics. It’s a good fit for growers who want a clear, mineral-forward bloom base designed for reproductive-stage performance, without turning their nutrient plan into a complicated process.

How To Use

How to Use Current Culture Bloom B - 1 Quart

Step-by-step mixing and feeding instructions for Current Culture Bloom B - 1 Quart.

Mixing & preparation

Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of Current Culture Bloom B - 1 Quart well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.

Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.

  • Use fresh nutrient solution whenever possible and avoid leaving mixed solution stagnant for long periods.
  • Store nutrients in a cool, dark place away from direct sunlight and extreme temperatures.
  • Keep bottles tightly sealed when not in use to reduce air exposure and preserve product quality.
  • Use clean measuring tools and regularly rinse or clean your reservoir, lines, and irrigation equipment.
Common mistakes to avoid
  • Do not mix different nutrients or additives together in concentrated form before adding them to water.
  • Do not exceed the recommended dosage unless you are following a tested, crop-specific feeding plan.
  • Do not skip pH or EC/ppm checks when growing in hydroponic or soilless systems.
  • Do not allow the nutrient solution to freeze or overheat, as this can damage the formulation.
  • Do not ignore the directions on the product label for your specific crop, growth stage, and system type.

Frequently Asked Questions
What does nitrate nitrogen (N) do for plants?

Nitrate Nitrogen provides a stable, easy-to-absorb form of nitrogen that supports steady growth, strong foliage, and reliable plant development without sudden nutrient swings.

Read the full guide

Why is soluble potash (K2O) important for plants?

Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.

Read the full guide

Why is water soluble magnesium important for plant growth?

Water soluble magnesium is important because it quickly restores the plant’s ability to make chlorophyll and produce energy, which helps stop interveinal yellowing on older leaves and improves overall nutrient use; it’s unique because it becomes available immediately in water, making it faster and more predictable than slower magnesium sources.

Read the full guide

Why is sulfur (S) important for plant growth?

Sulfur is important because plants need it to build key amino acids and proteins that drive real growth, strong structure, and efficient use of nitrogen, making it uniquely different from “look-alike” nutrients that may change leaf color without supporting the plant’s core building process.

Read the full guide

Is potassium nitrate better for quick deficiency correction than other potassium sources?

Potassium nitrate is often better for quick correction when the plant needs both potassium and fast nitrate nitrogen, because it dissolves cleanly and is taken up quickly, unlike potassium sources that don’t supply nitrogen. It’s unique because it can restore leaf color and growth momentum while also improving water regulation, but it can backfire if nitrogen is already high or if salt levels are already stressing the roots.

Read the full guide

What does magnesium sulfate do for plants?

Magnesium sulfate supplies magnesium for chlorophyll and sugar movement plus sulfur for protein building, helping plants stay efficient and green during high-demand growth. It’s unique because it adds magnesium without extra nitrogen or calcium, so it corrects magnesium issues with fewer side effects when balance is the real goal.
