How To Fix Calcium Nutrient Deficiency in Cannabis Plants

How To Fix Calcium Nutrient Deficiency in Cannabis Plants

Cultivating cannabis is a rewarding journey, but sometimes something gets in the way of an abundant harvest. A common issue is calcium deficiency in cannabis plants and the final yield suffers significantly if you don’t detect it fast. We share why calcium is crucial for crops and how to fix calcium deficiency in cannabis plants.

First, let’s talk about the need for calcium. Calcium is a vital nutrient to cannabis plants and is essential for optimal growth. This element plays a unique role in

Maintaining the expansion and
The structural integrity of cell walls

It also plays a central part in intracellular signaling. Plants such as cannabis that require a robust structure to support a large mass of vegetative and fruiting growth will have a higher demand for calcium. Due to this demand, calcium is required throughout most of the growing cycle, from the beginning of the vegetative phase through to the end of the flowering phase.

How to know if your Cannabis Plants have a Calcium Nutrient Deficiency?

All plants require a calcium source. Whether it’s coming from your water source or your fertilizer program, calcium is an essential secondary nutrient. When it is lacking, there are some tell-tale signs that are specific to calcium:

Low growth rate
Variable patterns of chlorosis on young leaves
Upward curling of leaves
Browning/necrosis of apical meristems (growing points)

How to use Cal Kick Cannabis Fertilizer

Plant-Prod MJ Cal Kick cannabis fertilizer was created with a traditional high calcium NPK formulation in mind, that was enhanced to meet the high demands of cannabis production. These enhancements include elevated levels of iron and the addition of a second chelating agent – EDDHA. Since this formulation contains nitrogen, potassium and a complete micronutrient package, it is ideal for alternating or simultaneous feeding with other growth stage-specific formulations.

Plant-Prod MJ Cal Kick cannabis fertilizer has a unique formulation that allows for this feeding without the risk of micronutrient deficiencies. Programs that rely on calcium nitrate fertilizer in Tank A do not have this option as the plants will be missing essential nutrients.

The micronutrient package allows for flexibility in feeding styles and ensures that at no point, are micronutrients deficient. Feeding rates should be based on water analysis to avoid overfeeding calcium. For more information on the A-B system and why this formulation cannot be mixed with others, see our previous post here.

The source of calcium in Cal Kick is calcium nitrate. This relatively reactive salt compound is frequently used to buffer coco growing media to replace potassium or sodium ions with calcium in cation exchange sites.

How to use Spike (CaMg) Cannabis Fertilizer

Plant-Prod MJ Spike (CaMg) was formulated to meet the needs of cannabis growers who desired to supplement calcium and magnesium without additional elements, such as nitrogen, sulphur or chloride. Spike (CaMg) contains chelated calcium and chelated magnesium, and nothing else.

It is intended to be used as a periodic supplemental source of calcium and magnesium, in addition to the standard 5 product Plant-Prod MJ program. Due to the lack of NPK and micronutrients, this product cannot substitute Cal Kick.

The source of calcium in Spike (CaMg) is EDTA chelated calcium. This metal complex is far less reactive to cation exchange sites than calcium nitrate and cannot be used in the same way to buffer coco media. The claw-like EDTA structure surrounding the calcium ion allows it to remain in solution and be more readily available for plant uptake.

Things to keep in mind when using Spike (CaMg) Cannabis Fertilizer

Plant-Prod MJ Spike (CaMg) is a unique product and should be used with the following in mind:

Use only as a supplemental feed at first sign of deficiency
Curb feeding to no more than twice a week, at low rates
Refrain from tank mixing with other Plant-Prod MJ formulations

The Problem With Hyperaccumulators: How to tell if you have contaminants in your Cannabis product.

The Problem With Hyperaccumulators: How to tell if you have contaminants in your Cannabis product.

Plants with the capability of accumulating heavy metals above concentrations that would typically cause harm or toxicity in plants are known as hyperaccumulators. Cannabis is a well-known hyperaccumulator with the ability to remove heavy metal contaminants from soils. This characteristic is desirable for soil remediation but troublesome when cannabis is grown for consumption.

If the nutrients you use are contaminated with heavy metals, your buds will be accumulating these heavy metals, exposing those who consume them.

The Problem: Cannabis Is A HyperAccumulator Of Heavy Metal Contaminants

Plants with the capability of accumulating heavy metals above concentrations that would typically cause harm or toxicity in plants are known as hyperaccumulators.

If the nutrients you use are contaminated with heavy metals, your buds will be accumulating these heavy metals, exposing those who consume them.

How can you tell if you have heavy metal contaminants in your final cannabis product?

We care about heavy metals just as much as you do

Licensed producers of cannabis are required to test their finished products for heavy metal contaminants. Plant-Prod® is pleased to make heavy metal analysis results available to growers for our Plant-Prod MJ™ water soluble cannabis fertilizers line. When cannabis growers are aware of heavy metal levels in their crop inputs, they can anticipate potential levels within their buds.

Plant-Prod MJ is growing

February 26, 2018Blogbud, calcium, cannabis, cannabis cultivation, chelated, magnesiumDoreen

Plant-Prod is pleased to announce a new addition to the Plant-Prod MJ product line, designed specifically for the cannabis industry – Plant-Prod ^MJ Spike (CaMg).

This new Spike (CaMg) fertilizer is made of exclusively chelated calcium (Ca) and chelated magnesium (Mg). Cannabis requires significant levels of Ca and Mg throughout the production cycle, especially during flowering and bud formation to ensure maximum yield.

The fact that this product is formulated with only chelates makes it truly unique. Chelated nutrients are far more accessible to plants and are immediately available to the roots. Most forms of Ca and Mg are either in sulfate, chloride or nitrate forms. Due to the high amount of Ca and Mg required, there is a greater chance of salt damage when using sulfate and chloride sources. In soilless media, many sulphate and chloride based nutrients are lost through leaching before they can become available to plants. When in the nitrate form, more nitrogen is provided to the system, compromising yield potential by confusing the cannabis plant. By adding excessive nitrogen at bud and flowering stages, plants will begin to grow vegetatively, shifting the plant’s focus from flowering to leaf and stem growth. Reducing overall yields.

Plant-Prod MJ Spike (CaMg) is formulated to give you the perfect ratio that cannabis plants need, 2 parts Ca to 1 part Mg, providing precise nutrition for maximum results.

Note that this product is not compatible with other Plant-Prod MJ^TM products. Please consult your Plant-Prod sales representative.

For full product information, see the Plant-Prod MJ Spike (CaMg) product page.

The new way to tote

Plant-Prod® provides soluble fertilizers to customers both in bags and in bulk. Customized formulations that are delivered in bulk simplify and speed up the preparation of large tanks of fertilizer solution. However, material compatibility limited the range of formulations available. This limitation is now behind us.

Our new Duo-Tote^TM has two compartments which keep incompatible ingredients apart, avoiding caking and melting, and allowing the delivery of all formulations. The contents of the Duo-Tote can be released at the same time where they dissolve quickly and without precipitating. Suitable for larger growers, the benefits of the Duo-Tote^TM are many:

One tote per tank – faster & easier

Formulated specifically for your size of tank and plant nutrition needs.
You need just one Duo-Tote^TM per tank, which is simple to use and minimizes the possibility of operator error.
The Duo-Tote^TM can be lifted over the tank using a hoist or forklift. The drawstring on the bottom releases the fertilizer into the tank.
No need to take delivery of numerous bags, each requiring time to open, lift and empty.
Speed up operations. Our customers report time savings of 75%.
