Top Fertilizers for growing your Marijuana Plant

Available on Amazon

To make it easier for you to choose the best fertilizer to feed your marijuana plants, we have listed below our top 5 best fertilizers you should check out. We share our top picks, complete with a stars rating on fertilizer products that have free shipping with Amazon Prime.

1.  Cutting Edge Solutions Uncle John’s Blend Growing Additive

Our first review looks at Uncle John’s Blend, which is a 0-0-2 formulated for use in hydroponic solutions. It can also be used as a foliar spray early on to give an additional boost. We rate this a 4 out of 5 stars, but only because it isn’t an organic fertilizer. If that doesn’t concern you, this one really packs a punch and it has a perfect 5 stars on Amazon at the time of writing. When it’s closer to your 12- hour light stage, add in some of their Bloom fertilizer product for professional results.

Features:

  • Increases your plants’ metabolic rate for a more healthier and perky plant.
  • Has complex, potassium based mixture that stimulates healthier photosynthesis cycles.
  • Has low molecular weight which means it won’t sit heavily on your plants.
  • Available in either bulk sizes or smaller 1-6 gallon sizes

Cons:

  • Somewhat pricey
  • FYI for organic weed growers – this fertilizer isn’t using an organic compound

Application: Twice a week.

 

2.  Fox Farm Liquid Nutrient Trio Product

Next up on our list is a review for Fox Farm – a leader in the organic fertilizer industry. This advanced formula will save you time trying to figure out what to feed and when. This trio of fertilizers gives you the right NPK formula for each stage of growing. We rate this one a 5 out of 5 stars for being the ultimate choice for beginner marijuana growers who want to keep things organic.

Features:

  • Use in sequence at each growing phase
  • Organic product
  • 3-step growth system that aids cannabis plants from initial planting to final stage of growth.
  • Has root stimulator which isn’t a common formula.

Cons:

  • None that we’re aware of!
  • Just be sure to follow the stages correctly

3.  Advanced Nutrients Big Bud Liquid Fertilizer

Our next report covers Big Bud, which was specifically formulated for cannabis grows by Advanced Nutrients. Made to work well with coco coir and other hydroponic mediums, we give this one a 5 out of 5 stars for sure.

4.  Flower Fuel 1-34-32 NPK

Talk about flower power! This one boasts a special blend of trace minerals and micronutrients, along with highly bio-available forms of phosphorus and potassium at a 1-34-32 NPK ratio. Mix 1/4 teaspoon per gallon of feed water. This marijuana fertilizer also works well with coco, soil or any nutrient base. This one gets a 4 out of 5 stars rating because it’s not 100% clear if all ingredients are organic and you’ll need to keep a close eye on PH levels immediately after use.

Features:

  • Great for any flowering plants and not just for marijuana
  • Has all the macro and micronutrients that your plant needs

Here’s a beginner’s perfect choice! This complete kit has 8 unique products that all serve different needs in a hydroponic cannabis operation. Perlite or vermiculite growers will appreciate this one for it’s easy application. We give this one a 5 stars rating, but only if you’re starting on a small scale because there is no bulk option.

Features:

  • Complete kit for hydroponics
  • Balances out PH levels
  • Reasonable price

Cons:

  • May cause fertilizer burn according to reviews

Whether you’ve already started growing marijuana or are just planning to get started, knowing what are the best fertilizers and nutrients is crucial. The cannabis plant is known for replenishing soil, but if you’re looking for the dankest buds with a rich terpene profile, you’ll definitely want to give them an added boost.

It may seem that everything is of equal importance when it comes to growing marijuana, but fertilizers and nutrients play a vital role in your plants’ health, growth potential, and potency. So, it is important that you choose the right fertilizers with the right nutrients to help your plant flourish. Read on for more information on caring for marijuana clones.

Fertilizers and Nutrients

A cannabis plant needs specific elements which are referred to as the “macro-nutrients” that cover both mineral and non-mineral elements. Micronutrients also play an important role in development and should not be ruled out! Many commercially available fertilizers have a special formulation of these trace elements along with the macro-nutrients to help boost your soil or hydroponics solution.

The three main macro-nutrients needed by your cannabis plants are nitrogen, potassium, and phosphorus which are found on every bag of fertilizer represented by 3 numbers printed on the front information section of the fertilizer container. These are often referred to as the N-P-K ratio. These numbers state what percentage of these 3 nutritional needs the fertilizer has and can provide your plant.

Aside from the above 3, there are other macro-nutrients needed by your cannabis plants as follows:

  • Hydrogen
  • Oxygen
  • Sulfur
  • Calcium
  • Carbon
  • Magnesium

In addition, your plant also needs a trace amount of some elements, namely:

  • Chlorine
  • Cobalt
  • Boron
  • Iron
  • Zinc
  • Molybdenum
  • Silicon
  • Copper
  • Manganese
