General Nutrient Basics

What are plant nutrients?

Plant nutrients are essential elements required for plant growth and development. They include macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), as well as secondary and micronutrients like calcium, magnesium, iron, and zinc.

What is the difference between fertilizer and nutrients?

Fertilizers refer to products used to supply nutrients to plants, while nutrients are the actual chemical elements that plants absorb for growth.

What does NPK mean?

NPK represents the three primary macronutrients:

• Nitrogen (N): promotes vegetative growth
  
• Phosphorus (P): supports root and flower development
  
• Potassium (K): enhances overall plant strength and yield
  

Why are micronutrients important?

Micronutrients such as iron, manganese, zinc, copper, and boron are required in small amounts but play critical roles in enzyme activity, photosynthesis, and metabolic processes.

​Liquid vs Powder Nutrients

What is the difference between liquid and powder nutrients?

Liquid nutrients are pre-dissolved solutions that offer fast absorption and easy application.
Powder nutrients are concentrated formulas that require mixing with water and provide flexibility in dosing and storage.

Are liquid nutrients better than powder nutrients?

Neither type is universally better.

• Liquid nutrients are ideal for precision feeding and hydroponics.
  
• Powder nutrients are suitable for large-scale cultivation and cost-efficient logistics.
  

Can liquid and powder nutrients be used together?

Yes. Many professional growers combine liquid base nutrients with powder boosters to achieve optimal nutrient balance and performance.

Which nutrient type is better for hydroponics?

Liquid nutrients are generally preferred for hydroponic systems due to their solubility and stability, but high-quality water-soluble powders can also be used.

​Feeding Program & Dosage

What is a feeding program?

A feeding program is a structured nutrient schedule that provides plants with the right nutrients at each growth stage, from vegetative growth to flowering and harvest.

How often should plants be fed nutrients?

Feeding frequency depends on plant species, growth stage, and cultivation method. Most systems follow weekly or bi-weekly nutrient adjustments.

How do I adjust nutrient dosage?

Start with a lower dosage and gradually increase based on plant response. Monitoring EC and pH levels is essential for precise adjustments.

What is EC and pH in nutrient solutions?

• EC (Electrical Conductivity) measures nutrient concentration.
  
• pH determines nutrient availability.
  Maintaining proper EC and pH ensures optimal nutrient uptake.
  

​Growth Stage Nutrition

What nutrients are needed during vegetative growth?

During vegetative growth, plants require higher nitrogen levels, balanced potassium, and sufficient calcium and magnesium to support leaf and stem development.

What nutrients are important for flowering?

Flowering stages require increased phosphorus and potassium to promote bud formation, flower density, and yield.

When should I switch from grow to bloom nutrients?

The transition typically occurs when plants enter the pre-flowering stage or when visible flower initiation begins.

What nutrients help increase yield?

Balanced NPK ratios, micronutrients, and targeted bloom boosters contribute to improved yield and crop quality.

​TCM Product Usage

Are TCM nutrients suitable for soil and hydroponics?

Yes. TCM Flourish products are formulated for both soil-based cultivation and hydroponic systems.

Can TCM nutrients be mixed with other brands?

TCM nutrients can be integrated with other nutrient programs, but compatibility testing and dosage adjustment are recommended.

Are TCM nutrients PGR-free?

Yes. TCM Flourish products do not contain banned plant growth regulators (PGRs).

Can TCM products be used as foliar spray?​

Some TCM products are suitable for foliar application. Always follow recommended dilution guidelines.

How do I use the TCM 3-Part Base Nutrient System?​

The TCM Flourish Series A, B, and C provide a complete nutritional foundation. Dosage and ratios should follow the TCM feeding chart.

Can Flourish Series A be used alone?​

Flourish Series A is part of the TCM 3-part nutrient system and is recommended to be used together with Flourish Series B and Flourish Series C for balanced nutrition.

What role does Flourish Series B play in the nutrient system?

Flourish Series B enhances nutrient availability and supports rapid vegetative growth by providing complementary macro- and micronutrients.

What is Flourish Roots used for?

Flourish Roots is a root enhancer designed to stimulate root development and improve nutrient uptake.

When should I apply Flourish Roots?

It is recommended during early growth, transplanting, and root establishment stages.

Why do plants need Calmag?

Calcium and magnesium are essential for cell wall formation, photosynthesis, and preventing nutrient deficiencies.

When should I use Calmag?

Calmag is recommended when plants show signs of calcium or magnesium deficiency or when growing in coco or hydroponic systems.

What is the benefit of silicon in plant nutrition?

Silicon strengthens plant structure, improves stress resistance, and supports heavy flowering.

What makes Flourish Aroma #18 different from other boosters?

Flourish Aroma #18 enhances metabolic activity, essential oil synthesis, and microbial activity in the root zone.

How does Flourish Sugar Shine improve flower quality?

Flourish Sugar Shine provides carbohydrates and magnesium to support flowering and aroma development.

What is TCM Grow Phase used for?

TCM Grow Phase is formulated to support vegetative growth by delivering balanced NPK and magnesium.

What is TCM Bloom Phase used for?

TCM Bloom Phase supports flowering by providing high levels of phosphorus and potassium.

​Nutrient Deficiency & Troubleshooting

How can I identify nutrient deficiency?

Common signs include yellowing leaves, slow growth, weak stems, and poor flowering. Each nutrient deficiency has distinct visual symptoms.

What causes calcium and magnesium deficiency?

Calcium and magnesium deficiencies often result from improper pH levels, nutrient imbalance, or insufficient supplementation.

What happens if plants receive too many nutrients?

Overfeeding can cause nutrient burn, leaf tip damage, and reduced growth. Proper monitoring of EC and pH is essential.

How can I correct nutrient imbalance?

Adjust nutrient ratios, flush the growing medium if necessary, and reintroduce nutrients gradually.

​Hydroponics & Growing Media

Are TCM nutrients suitable for hydroponic systems?

Yes. TCM nutrients are compatible with various hydroponic systems, including NFT, drip irrigation, aeroponics, ebb and flow, and deep water culture.

Can TCM nutrients be used in coco coir?

Yes. Dosage adjustments may be required due to the unique nutrient retention properties of coco coir.

What nutrients are recommended for drip irrigation systems?

Balanced liquid nutrients with stable solubility and low residue are recommended for drip systems.
