Best Nutrients for Cannabis

Using the best nutrients for cannabis is crucial when growing cannabis at home. It's really easy and can save you money and ensures you are getting the best quality cannabis. I'd recommend you use LED Grow Lights and grow tents to regulate your growing environment to get the highest quality cannabis. Its easier to grow in soil for beginners while hydroponically gives you the most control.  Either way, you will need to provide the correct nutrients for the stage of growth. Cannabis nutrients comes in different variations depending on your growing medium.

General Organics Go Box

Summary

The General Hydroponics General Organics Go Box is a good starter kit that includes everything you will need to grow cannabis. When I first started growing I used General Hydroponics as this was the only nutrient available at my local shop. It does a good job and is consistent but I prefer Advance Nutrients as they are specifically designed for cannabis.

Advanced Nutrients Bud Candy Fertilizer

Advanced Nutrients Bud Candy Fertilizer protects your seedling or clones during the first stage of growth. It can also be combined with other nutrients during the 6 weeks of flowering for higher potency and yields. Bud Candy enhances the flavour and aroma of your cannabis.

Advanced Nutrients Bud Candy Fertilizer provides the correct blend of carbohydrates for sweeter and much tastier buds. Some growers use molasses during the flowering stage but I find that Bud Candy is much better. Using Big Bud and Bud Candy together creates the ultimate flavour and highest potent cannabis. 

Sweeter and the biggest buds with sticky resin filled glands are a result. I find the taste and aroma to be incredible by just adding Bud Candy during the first 6 weeks of flowering.

  • Finer taste and aroma
  • Increased Potency
  • Easy to use

Summary

For the ultimate buds, I recommend you add both Bud Candy & Big Buds during the flowering stage. They also have a line of organic nutrients for the health minded grower.

Advanced Nutrients Big Bud Fertilizer

Advanced Nutrients Big Bug Fertilizer can be used in combination with your other nutrients during the flowering stage.  Developed to be added from the second week to the forth week of flowering. Big Bud provides all the essential micro-nutrients and 22 amino acids and are known to increase both the size and quality of your crop.

Start using Big Bud during the the second week of the flowering stage. You should see huge improvement in the size of your buds as they begin to swell. I really like using this in conjunction with Bud Candy. I saw an increase of nearly 20% in yields from my previous crop.

The Advanced Nutrients Big Bug Fertilizer contains potassium, amino acids and phosphorous to give you highest yields.

  • Larger, Heavier, denser buds
  • Buds with more essential oils, aromatics, terpenoids, phenols and other potency factors
  • Measurable, significant increases in overall harvest weight
  • Easy to use

Summary

Big Bud comes in a liquid and is easy to add to your existing nutrients. 92% of all growers use Advanced Nutrients Big Bud Fertilizer during the flowering stage. This should tell you something.

Advanced Nutrients B-52 Fertilizer Booster

Advanced Nutrients B-52 Fertilizer Booster is packed with all the essential B vitamins to enhance root growth and speed up seed germination.  It can use in soil and hydroponic gardens. You can use the Advanced Nutrients B-52 Fertilizer Booster during all stages but I would recommend you not use it for the first couple of weeks during the vegetative growth stage. 

The B-52 formula contains kelp and seaweed extracts. These extracts contain a variety of compounds, that increase cell replication and stimulate roots and stems. Folic acid ensures that your plants are remain healthy. Intense light breaks down Folic Acid so it's a good idea to add supplemental Folic Acid. During my last crop I added B-52 and saw a substantial increase in quality and higher yields. 

The Advanced Nutrients B-52 Fertilizer Booster contains all the B vitamins essential for strong root systems.

  • Folic Acid helps plants maintain healthy metabolism and DNA
  • Vitamin B5 is essential for fundamental cellular processes
  • Vitamin B1 (Thiamine) helps your plants use and create carbohydrates so your plants have enough energy to build strong vegetative growth and to power production of flowers
  • Increased in bud weight and potency as much as 31%
  • Easy to use

Summary

92% of all growers use Advanced Nutrients Big Bud Fertilizer during the flowering stage.  This should tell you something. As you can see, adding vitamin B complex to your nutrients is a good thing.  Give it a try and I'm sure you will be happy with the results.

My pick for the best nutrients for cannabis review, it's a no brainer, Advance Nutrients is the winner.

Best Nutrients for Cannabis

Identifying Nutrient Deficiencies

Nitrogen (N)

Nitrogen is required for all stages of growth but need more during the vegetative stage of growth. It is used in plant cells for the building blocks enzymes, protein and the green chlorophyll pigment. Chlorophyll is critical for plant growth, converting sunlight into energy in the form of carbohydrates and sugars.

Nitrogen Deficiency Signs

  • Stunted Growth, slower than expected
  • Yellowing of leaves, older leaves affected first
  • Purplish tints on the stems and underside of leaves
Phosphorus (P)

Phosphorus is important in energy transfer and storage in the plant. Without Phosphorus your plant will not be able to use the Nitrogen provided.

Phosphorus Deficiency Signs

  • Slow or stunted growth
  • Smaller leaves with blotchy spots
  • Reddish or purple leaf stems
  • Older leaves turn dark colours and curl downwards
Potassium (K)

Potassium is required for water uptake, flowering and cell wall development. Potassium keeps the sap stream and water flowing freely throughout the plant. It also helps plant resist environmental stresses, diseases and insects.

Potassium Deficiency Signs

  • Older leaves turning dull, yellowing and eventually developing rust coloured spots
  • Weak and brittle stems
  • Leaf edges look burnt, curled up leaves
Sulfur (S)

Sulfur aids in the production of essential amino acids, proteins and vitamins for chlorophyll production. It also plays a role in plant resistance of environmental stresses, diseases and pests.

Sulfur Deficiency Signs

  • Yellowing of all leaves
  • Buds dying off
  • Stiff and brittle leaves before falling off
Calcium (Ca)

Calcium builds strong cell walls and healthy root systems. Using too much Potassium can cause a deficiency in calcium, particularly if your soil has a low pH.

Calcium Deficiency Signs

  • Mottling or spotting of the leaf surface
  • Crinkling of leaves, curled tips
  • Stunted growth and smaller or deformed new leaves
Magnesium (Mg)

Magnesium is needed to move phosphorus around the plant and is important component in chlorophyll.

Magnesium Deficiency Signs

  • Yellowish or light green colouring of the veins and edges of older leaves
  • Brittle leaves
Trace Nutrients

These are required in trace amounts. Should be considered when selecting nutrients for growing cannabis.

  • Molybdenum (Mo): Involved in nitrogen metabolism
  • Copper (Cu): Needed to produce chlorophyll and for plant respiration
  • Zinc (Zn): Associated with chlorophyll production and protein synthesis
  • Manganese (Mn): Involved in growth, germination and new tissue production
  • Iron (Fe): Helps carry oxygen around plant cells and involved in chlorophyll production
  • Boron (B): Moves sugars around the plant and is involved in the uptake of calcium

The important thing to remember with all these nutrients is that they work together.

Often over or under feeding of a particular nutrient will cause the plant to block other nutrients from being uptake.  A well balanced nutrient developed for growing cannabis will ensure you get the most out of your indoor marijuana garden.

The best nutrients for cannabis is a personal choice amongst growers. You will find every grower has a personal favourite. I hope I've been able to help you with your choice.
