Why do plants have yellow spots?
Nutrient lockout is caused by nutrient buildup around a plant’s roots, or by pH imbalances, and prevents them from absorbing available nutrients. Nutrient lockout leads to nutrient deficiencies, which can cause yellowing foliage, burnt leaf tips, irregular leaf shape and size, and brown spots.
The first leaves
The leafy foliage of the cannabis plant grows in a series. Every series produces a certain number of leaves. Generally, the first series produces a single leaf. The second series will put out three leaves, the third series will produce five leaves, and so on.
Feeding seedlings
You’ll want to make sure your young cannabis seedlings get lots of nitrogen early on in their development.
Environmental factors
The rest of the environment is also something you want to make sure you are optimizing throughout every stage of growth, but particularly during the early phases. You have a couple options when it comes to lighting.
Vegetative stage
A good growth period will be followed by a strong flowering phase. As a grower, it’s your job to get your plants everything they need to develop properly before they flower.
Temperature, humidity and nutrients
Once your plants hit the peak of their growth phase, you can expose your plants to light for a full 24 hours, but it’s better to simulate night and give the plants up to six hours of darkness every 24 hours You’ll want sodium vapor or metal halide type lamps to make sure you’re providing the right kind of light.

Reading a Feed Chart for Growing Weed
Cannabis feed charts may vary in looks and format depending on the manufacturer, but generally have a similar structure that outlines how you should apply the nutrients.
Adjusting the Nutrient Schedule
When growing cannabis, there are tons of variables that influence the way you grow your plants. When it comes to the feed chart recommendations, there is no one-size-fits-all guideline for every type of plant. A company's recommendations are general guidelines that can be adjusted to fit the specific needs of your plants.
Cannabis Plant Feeding Schedule
Cannabis plants’s nutrient requirements vary depending on this strain, growing environment (soil or hydroponic), and stage of growth. Here's a general guideline for feeding plants throughout their seedling, vegetative, and flowering stages.
Regulating PPM and pH levels
When it comes to feeding your plants the right nutrients at the right time, there are a few other considerations to keep in mind:
Learn the Art of Cultivation
Cannabis Training University’s online learning platform provides new and seasoned growers with a complete curriculum covering every major aspect of the industry. Learn everything you wanted to know about starting your first garden and optimizing your set-up for bigger and better yields.
Home Grow Kits for Growing Cannabis

What is pH?
The pH indicates how acidic or alkaline a substance is. In order to optimally absorb all nutrients, the pH value around the roots has to be perfect. A wrong pH value causes your plants to not absorb all nutrients. This leads to a deficiency of certain nutrients in the plant, because the plant is unable to absorb the nutrients properly.
Nutrients
It’s best to use nutrients that was specially developed for marijuana plants, to know for sure the ratios are correct and you won’t have to worry about it. I use Flower Power Grow during the growth stage. But products by Fox Farm and Canna are also really good.
Pruning
Your marijuana plant needs to create a lot of sugars to be able to grow. It does so by converting light, water and CO2 into sugars and oxygen. Young leaves, new growth and side shoots use a lot of sugars, because they grow really hard.
Leaves
The leaves are the most important organs of a marijuana plant, because photosynthesis takes place in them. The leaf catches sunlight and converts this along with CO2 and water into sugars. Also, the stomata are located on the leaf. The plant can evaporate water, absorb CO and separate oxygen through these.
Root system
The roots are very important to a marijuana plant. Roots absorb water and nutrients, anchor the plant in the soil and certain hormones are made in the root system. Healthy roots have white tips with many root hairs. If your roots are brown, it indicates problems.
Most common bugs
I’ve already encountered thrips during this harvest, so you will probably also have to deal with bugs at some point. Outdoors it’s particularly hard to protect your plants against bugs. But indoor growers will also encounter bugs that are harmful to your plants.

Nutrients For Cannabis
Caring For The True Leaves
- After the young plants have 4-5 sets of true leaves, they are ready to be transplanted into a larger container where they will complete the rest of their growth cycle. The size of the container used will directly correlate to the overall space available in the growing area. Plants that have more space to grow can be grown in a larger container than if the growing area is more constricted. T…
Vegetative State Nutrition
- During the vegetative stage, the plant will require a base nutrient that is higher in nitrogen and lower in phosphorus and potassium. A base nutrient represents the main component of any fertility program (feeding schedule) and should contain the majority of essential elements needed for plant growth. Because of adverse interactions within the formulation itself, most base nutrie…
Water Quality
- It is also a good practice to use plain water in between feedings to avoid the possibility of excess nutrients accumulating and causing an imbalance of nutrients that can lead to them becoming unavailable to the roots. Another thing to keep in mind is how quickly the medium needs to be watered. Some mediums lose moisture faster than others so the more often the plant is being w…
Beginning A Fertility Program
- I recommend, especially for beginners, following the manufacturer’s suggested fertility program or feeding schedule. This is the best way to start on the right foot. After obtaining a good grasp on how the plants grow and react to different nutrient rates then you can start tweaking the program to improve plant development. Indoors, the vegetative stage is typically around 4 weeks from st…
