Should you defoliate cannabis when flowering?
The short answer is – yes, it is. It is a risky technique, sure, but you can defoliate autoflowers as well. As long as you remember to remove leaves in the vegetative stage, you’ll do good. But, don’t even think of applying any technique in the flowering stage lest you want the plants to yield tiny amounts of cannabis.
How often should I water my cannabis plants?
Well, some plants need to be watered every single day, and some only need to be watered every 2 to 4 days. The point here is that there is no exact rule when it comes to how often you need to water your cannabis plants. There are various factors which will go into determining this, and we are here to look at the most important ones today.
When to start flowering cannabis?

Feeding: This period (weeks 5 and 6) is considered peak flowering time for most cannabis strains. Make sure to keep a very close eye on your plants and look out for any signs of nutrient deficiencies or overfeeding.
When to stop feeding nutrients during flowering?
At the end of flowering, there may still be plenty of nutrients left in the growing medium and leaves. To prevent harsh tastes and unsavoury chemicals making their way into your stash, you can simply stop feeding any nutrients in the last 1.5–2 weeks of flowering.
How do you fatten up buds before harvest?
To some degree, more light translates to fatter buds and higher yields (you'll need to pay attention to the distance between your grow light and plants or your plant may suffer from light burn). Increasing light intensity is the most effective way to fatten up buds.
What nutrient is best for flowering?
To stimulate blooming, choose fertilizers with a higher percentage of phosphorus compared to the percentage of nitrogen and potassium. Healthy flowers start with vigorous root systems, and a potassium boost can ensure your flowers get a good start.
When should I stop feeding my plants?
Feed little and often instead of big, infrequent doses during the growing season and increase feeding with speed of growth. Stop feeding at the end of summer.
When should I switch from grow to bloom nutrients outdoors?
July–September: Your plants naturally shift from vegging to flowering as the light cycle changes. After the summer solstice, the days slowly become shorter, so expect to see the beginning of bloom phase. In the flowering stage, it's important to protect your outdoor crops from critters and pests.
Should I use nutrients every time I water?
You don't want to use liquid nutrients every time you water—use them every other watering, or two waterings on, one off. It depends on the complexity of your soil and the health of your plants. Too many nutrients will damage your plants. Giving weed plants the proper amount of nutrients requires careful monitoring.
Do buds grow during flush?
Plants, however, do not stop growing when they are being flushed. Rapidly expanding buds can be seen even while the flush is removing nutrients. High nutrient levels are not typical in nature, so when nutrients are encountered, all are welcome.
How to feed cannabis plants?
Just follow these steps: Prepare your water. If possible, heat your water to about 22°C to increase absorption by the roots. Add your nutrients according to the instructions on your fertiliser, and stir. Use a PPM or EC meter to get exact readings.
How do cannabis seedlings get nutrients?
Cannabis seedlings get all their nutrients from their seed, and absorb water via their leaves as their root system develops (that’s why it’s important to keep them in a warm, humid environment).
Why do plants burn?
Nutrient burn is usually caused by overfeeding or nutrient buildup in the grow medium. Plants develop dark green leaves with almost neon green tips that bend upwards almost 90°, and deep red, magenta, or purple stems or branches. Flowering plants develop yellow calyxes and sugar leaves before dying back rapidly.
How many nutrients does cannabis need to grow?
The higher the number for each value, the higher the concentration of that particular nutrient. However, cannabis needs more than just three nutrients to survive and thrive. It also counts on secondary nutrients like calcium, magnesium, and sulfur to play vital roles in plant growth:
What happens if you overfeed your plants with nutrients?
Going overboard with nutrients can result in chemical interactions or nutrient burn, which can significantly impact the size and quality of your yield. Once you’ve nailed feeding your plants with these core nutrients, feel free to move on to a more complex feeding schedule to produce bigger, more potent harvests.
What are the macronutrients in cannabis?
UNDERSTANDING CANNABIS MACRO AND MICRONUTRIENTS. Cannabis plants require three nutrients in large quantities. These macronutrients are nitrogen (N), phosphorus (P), and potassium (K), and they form the cornerstone of cannabis plant health. As such, these three nutrients usually feature front and centre on fertiliser products in the form ...
How to adjust pH of feed?
If necessary, adjust the pH of your feed using a nitric or phosphoric acid pH down supplement. Once your PPM, pH, and temperature are right, feed your plants and measure your runoff using your PPM or EC meter to ensure your plants are taking up their nutrients properly.
What does it mean when fertilizer goes with 2-6?
For example, if you see a label, stating the fertilizer goes with 2-1-6 N-P-K content, then this means you are holding a fertilizer with a big amount of Potassium, low amount of Nitrogen, and an even lower amount of Phosphorus. Apart from the basic nutrients, some essential macronutrients for healthy marijuana growth during flowering include ...
What are some examples of natural fertilizers?
For example, bat guano and earthworm castings make fantastic all-natural fertilizers.

Is nitrogen needed for marijuana plants?
However, marijuana plants require a greater amount of Nitrogen during vegetation and a lower ratio once they enter the flowering stage. That’s because Nitrogen is related to increased leaf growth, ...
When to switch cannabis plants from vegetative to flowering?
When To Switch Your Cannabis Grow From Vegetative To Flowering. When switching cannabis plants from the vegetative stage to the flowering stage , growers need to be aware of numerous considerations. Making the switch at the right time is crucial to maximising yield and avoiding complications.
When do sativas switch to indica?
Indicas are switched when they reach a height of around 100cm, giving them more time in the vegetative state. This method is designed to produce very heavy yields from a minimal number of plants.
Why are indicas and sativas different?
That is because indicas and sativas behave differently during flowering. Indica strains are known for producing shorter, thicker, bushier plants when compared to their sativa counterparts.
How long does it take for a plant to grow from seed?
Some growers believe that plants grown from seeds must be given 60 days of maturation in the vegetative state. However, this is not necessarily true. It is important to remember that young seedlings cannot start properly flowering for 2–3 weeks. However, when growing from clones, age is not an issue.
What is lollipopping in plants?
Lollipopping. Lollipopping is a technique that involves removing the lower growth of the plant that receives very little to no light. Because plants need light to grow, these regions will produce smaller buds and drain the plant of energy that could be better spent elsewhere.
Why is it important to know when to flip your plants?
This is because making the switch too early can result in a smaller total yield. Conversely, making the switch too late can result in overgrowth, or burned buds.
Why is it important to take a time period for a plant to grow?
This is important because complications and mistakes are much more difficult to recover from during the flowering stage. It should be noted that this time period is just a recommendation.
What nutrients do cannabis plants need?
As cannabis plants shift their nutrient demands during the flowering phase, they require less nitrogen and more phosphorus and potassium. If you look at any flowering nutrients for cannabis, you will see this shift represented in the N-P-K ratio on the bottle.
What is the N-P-K calendar?
To help alleviate any potential confusion around the N-P-K ratio, nutrient companies have developed feeding calendars to accompany their products. These calendars easily direct you on when to change nutrient regimes throughout a cannabis plant’s lifecycle. Importantly, calendars give you the ability to witness the N-P-K ratio changing from vegetative growth to flowering on specific dates.
What are bloom boosters?
These bloom boosters feature inflated N-P-K ratios for flowering that utilize much higher amounts of phosphorus and potassium.
How many hours of darkness does cannabis need?
Conversely, the flowering phase begins when cannabis plants receive 12 hours of uninterrupted darkness each day. This light schedule resembles the conditions of autumn in nature. When light periods change, cannabis is genetically wired to respond with specific growth phases. For cannabis plants to thrive in each of these growth periods, ...
Do bloom boosters work for cannabis?
Bloom boosters present a somewhat divided subject among cannabis growers. Many feel cannabis plants can only handle certain amounts of phosphorus and potassium — anything beyond that threshold is considered extraneous. Some growers swear by bloom boosters, stating they are necessary for a big harvest, while others take a more passive approach during flowering.
Is cannabis a photoperiodic plant?
Cannabis is a photoperiodic plant species. This means changes in daylight hours stimulate different growth phases in the plant. To illustrate, cannabis plants remain in vegetative growth when they have considerably longer days than nights (summertime).
