If you’re looking to grow your own professional cannabis plants, regardless of growing preferences, you should definitely go with the Plagron feeding chart. You can choose between various different growing methods, additives and even substrates from Plagron. With their feeding chart you’ll be able to follow clear instructions that can make for professional results in cannabis plants.

Plagron opened up for business back in 1992, when they started off as a simple worm farm that would one day turn into an international leader when it comes to plant fertilizers. The best thing about this high-end fertilizer brand is the wide variety of products that they have in stock. If you already know about Plagron, go ahead and skip to the feeding charts – we’re going to do a quick run-through of some of their best products.

They have quite an efficient yet simple way of categorizing their products into colors:

  • Green: NATURAL
  • Red: TERRA
  • Blue: HYDRO
  • Orange: COCO
  • Purple: UNIVERSAL

This means that you can choose the right substrate and corresponding base fertilizers, alongside the Plagron universal additives.

Plagron Feeding Chart Substrates

Thanks to the amount of diverse products that Plagron has to offer, you can choose from a large list of different substrates; they stock organic, mineral and even coco coir substrates. Each substrate is reflected in the Plagron feeding chart below.

Lightmix: This substrate doesn’t contain many nutrients, which allows you for a more rigorous control of your plants’ feeding schedule. When you grow cannabis using this substrate, you’ll need to be quite on top of them and add any extra nutrients using base fertilizers and additives. This substrate contains non-organic minerals.

Growmix: This is a heftier version of the previous substrate, as it contains the perfect proportion of nutrients to feed your plants during the first few weeks of their growth process. You won’t need to fertilize as much when using this type of substrate. This substrate also contains non-organic minerals.

Allmix: This substrate is absolutely choc-full of organic nutrients, which is why we highly recommend it for organic, natural growers. It comes with plenty of nutrients too, so you shouldn’t even need to use a base fertilizer for the growth period, which could cause accidental over-feeding.

Royalmix: Just like Allmix, this substrate contains quite a high amount of nutrients. In fact, if you wanted to grow your plants using just this substrate without needing to add any other fertilizers, you’d probably get some pretty decent results. All you have to do is adjust your pH when you water your plants, although if you use additives you’ll get some of the best possible results.

Batmix: This particular substrate is designed to allow you to improve and increase aroma, effect and flavor in your buds in a fully organic manner. It’s great for autoflowering plants, allowing you to grow them without needing to use anything but pure water. The best results are obtained from seasonal strains, however, and when used alongside the necessary additives.

Plagron Feeding Chart Base Fertilizers

Alga Grow & Bloom: These two products are organic base fertilizers used in cannabis plants. They have a high content in natural algae – we do not recommend using these products in drip irrigation or automatic systems, as it does not fully dissolve and may end up blocking your pipes. Grow & Bloom are sold separately, and if you use a nutrient-rich substrate you may not even have to use Alga Grow.

Terra Grow & Bloom: These bases are mineral in origin and you can use them to obtain some truly professional results. Terra Grow contains a little extra nitrogen, which is exactly what your plants need during the growth period, whereas Terra Bloom contains much more potassium and phosphorus, which are needed in larger amounts during the flowering period.

Cocos A & B: This two-part base fertilizer is highly concentrated. They’re specifically made for growing in coco coir substrates, adjusting the pH of your water automatically so that you don’t have to. Keep in mind that coco coir substrates come with hardly any nutrients at all, which is why giving them such an intense diet is so important.

Hydro A & B: Another two-part base fertilizer, Hydro A&B is a product that’s designed specifically for hydroponic growing. It contains all of the necessary nutrients for plants grown hydroponically, and it won’t block any of your pipes or cause any sort of damage. When grown in an aquatic medium, the only source of nutrients that your plants have is what you give them via the water, so you’ll need to keep this in mind. That’s why Hydro A+B is such a highly concentrated product.

Plagron Feeding Chart Additives:

Power Roots: This particular additive is used to stimulate your plants’ roots – it’s one of Plagron’s universal products which is generally used with every different feeding chart in order to increase root size. Regardless of your preferred growth method, you can use Power Roots in order to increase the size and health of your cannabis roots.

Vita Race: If you’re looking for a potent growth and flowering stimulant, Vita Race is the perfect additive for you. Give your plants a little extra iron in order to keep them strong and green. Iron is incredibly important to cannabis plants, and if you give them a little extra all of these important processes are accelerated and stimulated. Your plants will grow much stronger, capable of absorbing more energy from the light and improving their metabolism in general. This product is used once a week exclusively as a spray.

Green Sensation: This additive is used alongside the necessary base fertilizers during the bud-fattening period. It can be used to increase and improve the flavor and aroma in your buds, as well as considerably increasing yield. This universal product can be used in any growing medium.

Pure Zym: This particular combination of enzymes is capable of helping you to increase microbial life in your cannabis plants’ substrate. Essentially, it tracks down your plants’ dead roots and turns them into nutrients that they can absorb. It also frees up a lot of space for new roots to grow where the dead ones were – this increases root size and therefore, plant size in general.

Other Products

The products we just covered are main ingredients in the Plagron feeding chart, however they have quite a lot of other more specific products such as pH adjusters and root stimulants for saplings and seeds.

Calcium Kick: this product is used to adjust any calcium or magnesium deficiencies in your plants, which tend to be the culprit of certain issues once your plants begin to flower. If you use pure or osmosis water, you will need to use this product. It’s also capable of adjusting the pH in your substrate.

Seedbooster Plus: If you tend to have issues when it comes to germinating your seeds or you’re simply looking to accelerate the process, Seedbooster Plus by Plagron can give you a hand with that. It gives seeds an incredibly small amount of nutrients and enzymes, and it can be used to revive old seeds and make them germinate. It also gives your plants enough nutrients to stimulate the first few roots and initial growth.

pH +/-: Some of Plagron’s products can adjust pH automatically, although not all of them can – that’s why they have specific pH adjusters for increasing or lowering acidity, as well as a fully organic pH- product for the flowering period, which is made out of citric acid.

How to use the Plagron Feeding Chart

One of the most basic things to keep in mind is that you’ll need to measure and adjust your pH as is needed while growing. Plagron feeding charts indicate the EC that your plants should be receiving each week. The amount of nutrients that your plants can absorb is directly affected by the pH of the nutrient solution you’re feeding them with. The most recommended pH for cannabis plants is between 5.5 and 6.5, although it can be adjusted even further depending on the method used and the phase your plants are in.

All measurements are per 10L of water, and the EC values assigned are for tap water – regardless, EC should never go over 3.0.

Organic Chart

If you plan on growing using organic nutrients, this is the feeding schedule you’re looking for. It has various different substrate choices, all of which are organic, and it also comes with Plagron’s universal and organic additives. Keep in mind that feeding charts are a simple guide; you may be growing a sativa plant outdoors, which will need more growth and flowering weeks. In cases such as these, you’ll need to use this chart as a guide, adding more growth or flowering weeks if necessary. The reaction that your plants have to this feeding schedule may differ depending on the strain, your climate and how much experience you have.

ALWAYS flush your plants’ roots out towards the end of the flowering period. This can be done by using just water for a week or two or by using a specific product designed for flushing plant roots.

Soil Chart

This chart is for those that would prefer to grow in soil and use mineral products. You can choose between two different substrates and use all of their universal additives that make for some of the best possible results. Keep in mind that feeding charts are a simple guide; you may be growing a sativa plant outdoors, which will need more growth and flowering weeks. In cases such as these, you’ll need to use this chart as a guide, adding more growth or flowering weeks if necessary. The reaction that your plants have to this feeding schedule may differ depending on the strain, your climate and how much experience you have.

ALWAYS flush your plants’ roots out towards the end of the flowering period. This can be done by using just water for a week or two or by using a specific product designed for flushing plant roots. Make sure to try and keep your EC at the same level indicated in the chart – these levels indicate the EC of your nutrient solution after adding the necessary products for that particular week. EC should never go over 3.0.

Coco Chart

For those that prefer to grow using coco coir slabs or bricks, this feeding chart contains the perfect doses of nutrients; coco coir is quite poor in nutrients, which is why this chart is so stacked. You’ll still need to keep in mind that feeding charts are a simple guide; you may be growing a sativa plant outdoors, which will need more growth and flowering weeks. In cases such as these, you’ll need to use this chart as a guide, adding more growth or flowering weeks if necessary. The reaction that your plants have to this feeding schedule may differ depending on the strain, your climate and how much experience you have.

ALWAYS flush your plants’ roots out towards the end of the flowering period. This can be done by using just water for a week or two or by using a specific product designed for flushing plant roots. Make sure to try and keep your EC at the same level indicated in the chart – these levels indicate the EC of your nutrient solution after adding the necessary products for that particular week. EC should never go over 3.0.

Hydro Chart

For the fastest and biggest results, we recommend growing hydroponically. Your plants’ only nutrient source in aquatic media is whatever you decide to give it via water, so you’ll need to keep a close eye on your plants when grown hydroponically. Keep in mind that feeding charts are a simple guide; you may be growing a sativa plant outdoors, which will need more growth and flowering weeks. In cases such as these, you’ll need to use this chart as a guide, adding more growth or flowering weeks if necessary. The reaction that your plants have to this feeding schedule may differ depending on the strain, your climate and how much experience you have.

Make sure to try and keep your EC at the same level indicated in the chart – these levels indicate the EC of your nutrient solution after adding the necessary products for that particular week. EC should never go over 3.0.

All the nutrients needed for cannabis plant development are naturally present in the environment. However, to help your plants develop even faster and produce a better end product, you’ll want to feed them with fertiliser—concentrated nutrients.

Below, you’ll find all the information you need to know about when, how, and how much to feed your cannabis plants.

UNDERSTANDING CANNABIS MACRO AND MICRONUTRIENTS

Cannabis plants require three nutrients in large quantities. These macronutrients are nitrogen (N), phosphorus (P), and potassium (K), and they form the cornerstone of cannabis plant health. As such, these three nutrients usually feature front and centre on fertiliser products in the form of an NPK ratio. The higher the number for each value, the higher the concentration of that particular nutrient.

However, cannabis needs more than just three nutrients to survive and thrive. It also counts on secondary nutrients like calcium, magnesium, and sulfur to play vital roles in plant growth:

  • Calcium is important for cell wall development, can help reduce soil salinity, and improves water penetration when used as a soil amendment.
  • Magnesium plays a key role in photosynthesis and carbohydrate metabolism, and also helps with the stabilisation of plant cell walls.
  • Sulfur is necessary for the formation of chlorophyll and the production of proteins, amino acids, enzymes and vitamins, and protects plants against disease.

Beyond this, plants also make use of several other nutrients in small quantities (micronutrients) that are nevertheless extremely important. These include boron, chlorine, copper, iron, manganese, molybdenum, and zinc. While these aren’t the main nutrients plants use for food, they still play very important roles in various aspects of plant health.

NOT ALL CANNABIS FERTILISERS ARE MADE EQUAL

There are many different brands of cannabis nutrients on the market, and they can differ considerably.

Typically, cannabis fertilisers will vary in the four following areas:

  • Nutrient ratio: Different brands use different nutrient ratios they consider optimal.
  • Ingredients: Different fertiliser brands can achieve the same nutrient ratios using completely different ingredients, ranging from the most chemical (or “artificial”) to the most natural.
  • Soil or hydro: Soil nutrients are very different from hydro or soilless nutrient solutions. Make sure you only use fertilisers designed for your growing medium.
  • Supplements: Many fertiliser brands also make “supplements”. These products typically contain low NPK ratios and instead feature other nutrients designed to boost certain aspects of growth. Some supplements, for example, are essentially molasses.

In general, we recommend you focus more on meeting your plants’ demands for macro and secondary nutrients before pumping them full of supplements. Going overboard with nutrients can result in chemical interactions or nutrient burn, which can significantly impact the size and quality of your yield.

Once you’ve nailed feeding your plants with these core nutrients, feel free to move on to a more complex feeding schedule to produce bigger, more potent harvests.
