  • Your plants will need three primary (macro nutrients): nitrogen (N) for vegetative growth, phosphorus (P) for root and flower development, and potassium (K) for overall plant health and stress resistance.

    However, plants also require various micronutrients which are needed in smaller quantities to support specific metabolic functions. These include calcium, zinc, magnesium and iron.

  • Plants require different amounts of nutrients at different stages of growth, and while some brands of nutrients can be used throughout the entire cycle, we have developed a range of products which provide the correct levels of nutrients at the right time when the plant needs them.

  • Yes! Our Pro Series is designed to be used alongside our other nutrients. Replace PK Phite with PK Ultra, Foundation with Roots Ultra and add Silicon Ultra at the dosage stated on the Pro Series grow schedules which can be found HERE

  • It’s recommended that you feed your plants once a week. Refer to our grow schedules for exact dosages of each nutrient.

    You can find our grow schedules HERE

    And our Pro Series grow schedules HERE

  • While you can, it’s not recommended that you mix brands together during a grow.

    Different brands use different nutrient ratios they consider optimal and different fertiliser brands can achieve the same nutrient ratios using completely different ingredients.

    Every brand develops their nutrients to work symbiotically with the others,

    So if you mix and match brands the strength of your nutrient mix is likely to be too high or too low, putting the health of the plant at risk.

  • For the environmentally conscious grower, we have developed Organix Grow and Bloom which will feed the beneficial fungi and micro organisms within the growing media without the need for any additional chemicals.

    Find Organix HERE

    Organix Grow and Bloom are packed with the micro and macronutrients needed to stimulate growth and improve soil structure leading to the development of strong shoot formation and fantastic blooms!

    If you want to add more organic fertiliser then consider the following:

    Worm Castings: Worm castings, also known as vermicompost, are the rich, dark organic material produced by earthworms during the decomposition of organic matter.

    Guano: Guano is bat or seabird droppings that have accumulated over time and are rich in nitrogen, phosphorus, and potassium.

    Seaweed and Kelp Extracts: Seaweed and kelp extracts are derived from marine plants and are a natural source of essential nutrients, growth hormones, and trace minerals.

    Bone Meal: Bone meal is made from finely ground animal bones and is a good source of phosphorus and calcium.

    Alfalfa Meal: Alfalfa meal is derived from dried alfalfa and is a natural source of nitrogen and other essential nutrients.

    Fish Emulsion: Fish emulsion is a liquid fertiliser made from fish waste and contains nitrogen, phosphorus, and trace minerals.

  • We have developed Coco A and B to be used when growing using coco coir and Dirt Grow and Bloom for growing in soil. This is due to the varying nutrient retention capacities and chemical properties of these two growing mediums.

    Coco coir is an inert growing medium, which means it has little to no inherent nutrient content. While it has a good cation exchange capacity (CEC) compared to other inert mediums, it still retains certain nutrients less effectively than soil.

    Calcium and Magnesium: Coco coir tends to have lower natural calcium and magnesium levels than soil. To address this our Coco has higher amounts than you'll find in our Dirt Grow and Bloom.

    Potassium: Coco coir has a good cation exchange capacity (CEC), but it still retains potassium less effectively than soil. Soil generally retains potassium well, so liquid fertilisers for soil will contain slightly higher potassium levels compared to those for coco.

    Balanced pH Levels and adjustments: Coco coir has a natural pH that tends to be slightly acidic. Coco has been designed to have a balanced pH to ensure the nutrient solution stays within the optimal range for nutrient uptake. Soil pH can vary depending on the specific type of soil Dirt Grow and Bloom contains pH-adjusting agents to help maintain an optimal pH range for nutrient availability.

    It's Important to use nutrients which are specifically formulated for the intended growing medium to ensure optimal nutrient availability and avoid potential nutrient imbalances or deficiencies.

  • In hydroponics, you can adjust nutrient levels by changing the strength and composition of the nutrient solution. Regularly monitor the pH and electrical conductivity (EC) to fine-tune nutrient delivery.

    For monitoring the pH there are several methods for doing this:
    A pH meter
    pH test strips
    pH colour chart kits
    pH drops

    For testing the EC:
    EC Meter (TDS Meter)
    EC Tester Pen

  • Nutrient lockout in hydroponics refers to a situation where certain essential nutrients become unavailable or inaccessible to the plant roots despite being present in the nutrient solution.

    The most common cause of nutrient lockout in hydroponics is related to the pH level of the nutrient solution. To prevent this you should:

    1) Regularly check and maintain the pH level of the nutrient solution within the recommended range for the specific plants being grown. For most hydroponic crops, a pH range of 5.5 to 6.5 is commonly used. Use Down N' Dirty to bring the pH of your nutrient solution down

    2) Ensure that the nutrients are mixed accurately and in the correct order to prevent any chemical reactions that might result in precipitation or nutrient interactions.

    3) Keep your hydroponic system clean and free from debris to prevent clogs and blockages that could disrupt nutrient flow. Use Down N' Dirty to prevents mineral deposits within reservoirs, pipework and pumps.

  • Our Coco, 60/40 and Hydro base feeds come two parts to ensure nutrient stability and pH adjustment.

    Combining all nutrients into a single solution can lead to undesirable reactions and nutrient precipitation and binding.

    The two-part system allows experienced growers to customise nutrient ratios for different growth stages, providing precise and balanced nutrition.

    It also offers versatility, making adjustments based on specific growing conditions and water quality. Separating the nutrients maintains stability, allow pH control, and provide better nutrient management.

  • YES! Our Wideload is our booster nutrient.

    It contains a powerful blend of plant extracted bio-stimulants which speed up plant development which leads to faster finishing and consistently higher yields and quality.

  • Not any more!

    Our Silicon Ultra is the same fantastic nutrient but now it's odourless.

    Check out our Ultra grow schedules for dosages.

  • Many booster nutrients contain certain organic or mineral compounds that are not fully soluble in water. When used in hydroponic systems, these compounds can accumulate and adhere to the inner surfaces of the pipes.

    We advise using our Down N' Dirty which has been designed to prevent mineral deposits within reservoirs, pipework and pumps.

    Also ensure proper pH levels and nutrient ratios in the solution.

  • Our Silicon Ultra can be applied by foliar. To make your spray use 0.1ml per litre of water.

  • No our Wideload Boost contains a powerful blend of plant extracted bio-stimulants but not triacontanol.

  • Yes!

    Down N’ Dirty is specifically designed to quickly bring the pH of your nutrient solution down for any type of substrate, without harming the microbes in the soil.

    By optimising the balance between acidity and alkalinity accelerates growth and prevents deficiencies occurring in the plant.

    You can also use Down n’ Dirty to prevents mineral deposits within reservoirs, pipework and pumps.

  • We are currently developing a pH Up so watch this space!

  • In the UK the distribution of soft and hard water varies across different regions so it is very difficult to create grow schedules for every situation.

    As a guideline, if you live in a city or large town you are likely to have hard water.

    If you live in very rural areas such as Northern Ireland, Northern Scotland or rural Wales you will likely have soft water. If you use distilled water or rain water for growing then this will be soft water also.

    Our grow schedules provide dosages which suit a median water hardness and will not damage your plants if your tap water is a bit above or believe the average.

    If you think your water is overly hard or soft, purchase a Water Hardness Test Kit to see and then adjust your nutrients accordingly.

  • Providing specific EC and pH guidelines for all possible scenarios can be challenging. For example cultivation can vary significantly depending on factors such as what you are growing, the medium you are growing it in, the hardness of your water and environmental conditions.

    As a general guide:

    EC would scale from 1.2 in week one to 2.2 in week 7 then drop to 1.9 before flush

    EC closed room would scale from 1.4 in week one to 2.8 in week 7 then drop to 2.2 before flush

    It's generally recommended to keep pH between 6.0 and 6.5 for soil and 5.5 and 6.5 for hydro, but again this very generalised and we recommend you monitor your EC and pH consistently and adjust your nutrient solution accordingly.

NUTRIENT DEFICIENCIES

And how to fix them!

  • Symptoms: Yellowing (chlorosis) of lower leaves, starting from the tips and spreading inward, while the veins remain green. Overall plant growth may be stunted.

    Solution: Increase the nitrogen levels in your nutrient solution by using a fertiliser with a higher N content. Ensure the pH of the medium is within the appropriate range (around 6.0-6.5 for soil, 5.5-6.5 for hydroponics) to improve nutrient uptake.

    We suggest adding our Organix Grow as it has a relatively high nitrogen content at 5%.

  • Symptoms: Slow growth, darkening of leaves, and purplish or bronze discolouration on older leaves. Reduced flower production and smaller buds can also occur.

    Solution: Use a fertiliser with a higher phosphorus content during the flowering stage. Additionally, adjust the pH to ensure proper nutrient absorption by the roots.

    We recommend using our Organix Bloom which has a relatively high phosphorous content of 5.0%

  • Symptoms: Yellowing and curling of leaf edges, followed by necrosis (death) along the edges. Lower leaves may show signs of burning or dying.

    Solution: Increase the potassium levels in your nutrient solution by using a fertiliser with higher K content. Maintain proper pH levels to facilitate nutrient uptake.

    We recommend increasing your dosage of PK Phite ( or PK Ultra ).

  • Symptoms: Inter-veinal yellowing on older leaves, with the veins remaining green. Leaves may curl or cup downward.

    Solution: Apply a magnesium supplement to the nutrient solution or increase your dosage of Mag-Cal. Alternatively Epsom salts (magnesium sulphate) can be used as a quick remedy by dissolving it in water and applying it as a foliar spray or in the nutrient solution.

  • Symptoms: New leaves show distorted growth and may develop dead spots or necrosis. The overall plant structure may be weak, leading to stem issues.

    Solution: Use a calcium supplement in your nutrient regimen or increase your dosage of Mag-Cal. Additionally, check the pH levels to ensure optimal nutrient uptake.

  • Symptoms: Younger leaves display yellowing between veins, while the veins themselves remain green. This creates a “inter-veinal chlorosis" pattern.

    Solution: Use an iron supplement, like chelated iron, to correct the deficiency.

    Ensure the pH is in the proper range to improve iron availability to the plants.

  • Symptoms: Yellowing of newer leaves, starting from the tips and spreading inward. Leaves may also become smaller and have a thin, brittle appearance.

    Solution: Increase your dosage of PK Ultra. Adjust the pH levels to enhance nutrient absorption.

  • Symptoms: Reduced inter-nodal spacing, smaller and distorted leaves with inter-veinal chlorosis.

    Solution: Apply a zinc supplement to your nutrient solution. Ensure the pH is within the appropriate range for optimal zinc uptake.
