Marijuana Nutrients

No matter whether you’re cultivating regular seeds, feminized or autoflowers, every gardener needs some marijuana nutrients! 

Fertilization in plants is an extremely important part of the growth cycle of basically every plant, particularly the types of plants that provide growers with something of value, meaning produce. 

Given society’s general move towards being more conscious of the environments and the natural world around them, most farmers, gardeners, and cultivators are now trying to use more natural fertilizer for plants or organic fertilizer for plants.  

What’s the Difference Between our Standard Cannabis Fertilizer and our Organic Marijuana Nutrients?

With this in mind, we decided to offer two different packs of nutrients, one being the standard pack and the other being a completely organic nutrient pack. These packs consist of four products each to reflect the different growth stages of the plant. 

Marijuana Nutrients for the Seedling Stage

For the early life of your marijuana plant(s) we have the Seedling Booster, this bottle ensures that you can meet the marijuana nutrient requirements at the beginning of their life, building resistance to any potential threats that they may be susceptible to at this baby stage. 

The standard nutrient bottles contain a number of essential nutrients, chief among them are monopotassium phosphate, diammonium phosphate, potassium nitrate, and potassium sulfate. In terms of our alternative pack of natural fertilizer for plants, the Seedling Booster contains amazing marijuana nutrients derived from rock phosphate, soy protein hydrolysate, calcium carbonate, magnesium sulfate, and kelp extract.

Marijuana Grow Nutrients for Vegging Plants

Once weed plants begin to transition and grow into the vegetative stage, they will require different marijuana nutrients. Predominantly, in the vegetative stage, your plants will require essential nutrients derived from monopotassium phosphate, diammonium phosphate, potassium nitrate, and potassium sulfate, all of which are packed into the standard bottles. While in our packs of organic fertilizer for plants, we have a mix of nutrients derived from calcium, magnesium, water-soluble manganese, water-soluble zinc, water-soluble boron, water-soluble copper, and water-soluble iron. All these serve your plants as the best plant fertilizer for this particular stage of growth.

Cannabis Flowering Fertilizer

In the Flowertime Fertilizer bottles, you will find cannabis flowering fertilizer to help support your plants in the later stages of the growth cycle. The standard pack of marijuana nutrients contains essential nutrients such as monopotassium phosphate, diammonium phosphate, potassium nitrate, and potassium sulfate, all of which will be of great help to your plants during the flowering period of the plants growth.

While, in the pack of organic fertilizer for plants is packed full of rock phosphate, soy protein hydrolysate, ferrous sulfate, manganese sulfate, zinc sulfate, sodium borate, potassium sulfate, potassium chloride, copper sulfate, magnesium sulfate, and kelp extract. All of these should be enough to ensure the flowering phase of your cannabis plants is successful.

Use these Extra Marijuana Nutrients to Grow Plants with Big Buds

The final product in both plant fertilizer packs is Plant Booster which will help give your cannabis plants that little extra help, this particularly comes into use if your plants are from fast-growing seeds or autoflowering seeds. This is the best way to cap off our packs of the best fertilizer for indoor cannabis plants, however, this is not simply great indoor plant fertilizer, it also works great for growing outdoors.

How to Feed Marijuana Nutrients 

You can add the best nutrients for marijuana plants into the water you use to feed your plants. All of our standard plant fertilizer and organic fertilizer for plants contain water-soluble nutrients. This means you should have no issue amending your water with nutrients to provide your plants with everything they need. 

While perhaps these are best used as indoor plant fertilizer, you can use them outdoors but you will just need to alter the amounts slightly in-line with the needs of your plants. 

More than the Best Marijuana Nutrients

To push your growing abilities further and help you out that extra little bit, we are offering a third product consisting of different plant protectants to help guard your plants against mold, bugs, germs and offer protection to the all-important roots.

Marijuana Nutrients FAQs

When feeding cannabis nutrients, you can encounter a number of different issues. A lot of problems relating to marijuana nutrients are providing them with too much or too little. 

What are Marijuana Nutrient Deficiencies?

When your cannabis plant isn't getting enough of a certain nutrient it will begin to suffer, this is what we call a nutrient deficiency. If you're not using the best fertilizer for cannabis then there is a good chance you will encounter a nutrient deficiency. If you consult a marijuana nutrient deficiency chart, you will surely be able to understand which nutrient your plants are missing.  If your plants are lacking any Macronutrients also known as the NPK nutrient trio (Nitrogen, Phosphorus, and Potassium)  you will begin to see the signs almost immediately. However, the same also applies to Micronutrients such as Calcium, Magnesium, and Sulphur.

The most common forms of nutrient deficiencies are Nitrogen deficiency, Phosphorus deficiency, and Potassium deficiency, however, Calcium deficiency and Magnesium deficiency are also pretty common. If you were to even try growing marijuana without nutrients, you would surely encounter this problem immediately, that is why it always best to ensure you have the right volume of marijuana nutrients before you grow.

How do you Stop Nutrient Burn Marijuana?

Nutrient burn marijuana occurs when cannabis growers provide their cannabis plants with excess nutrients. One way to spot cannabis nutrient burn is by looking at the leaves, more specifically the tips of the leaves. Marijuana nutrient burn often manifests as yellow or brown leaf tips, instead of the usual green color. Leaves start to die if left untreated.

If you’re using soil or some other hand-watering system, one way to combat cannabis nutrient burn is by flushing your plants of all the marijuana nutrients as you would in the weeks before harvest. After flushing, you must amend the nutrient solution to provide your plant with optimum nutrients. To do this, you must run clean, pH-ed, nutrient-free, water through your plants. Wait until your plant has used the last remaining nutrients in the grow medium and then start feeding again. However, this time you must amend your feeding with the best nutrients for weed, paying close attention to what imbalances it had before. 

If you’re experiencing marijuana nutrient burn in your hydroponics system, the method for combatting it is similar but not completely the same as a hand-watered system. You should dilute your reservoir with plain, pH-ed water or, in extreme cases, completely change the water.

Going forward, use a TDS meter to regularly monitor the nutrient content of your reservoir. Be aware that old, affected leaves will not recover, but if you’re going in the right direction then new growths should not be impacted.  If you choose any of our best hydroponic nutrients for marijuana then you should have the perfect quantities of nutrients. You should refer to the feeding schedules provided to ensure you don't over or underfeed your plants.

If you’re not in possession of a TDS meter, the best solution is to start feeding your plants low levels of nutrients and build your way up.

Nutrient burn is not the end of your plants, healing them need not be difficult.
