Defoliation: Stop feeding the plants. Instead, flush them with a flood of water and then defoliate with a pair of shears . Defoliation helps the plants absorb more light while limiting the risk of damaging mold.
Flowering: Sticky, resinous buds will make their first appearance during week five, giving you a preview of the bounty to come. Keep the humidity consistent at 45 percent but increase the temperature to about 71 degrees. Increase the water to a full liter each day and add supplement tablets twice a week. Look for those containing phosphorus, calcium, magnesium, and potassium.
Here are four of the top reasons to grow autoflowering cannabis:
Cannabis seeds seem to be available in limitless options and it can be confusing when you have to choose. Should you go with feminized seeds? What about autoflower seeds?
Photosynthesis: Add more nutrients to your late-stage seedlings. Since you are growing autoflowers and not regular seeds, use only half the usual dose indicated on the package.
As the name implies, autoflowers automatically shift to the flowering period without intervention. Whereas the flowering of photoperiod plants is dependent on cycles of light and dark, autoflowers zip through this growth stage according to their age. Autoflowering cannabis seeds may mature in as little as seven or eight weeks from seed to harvest depending on the strain .
Maintenance: It’s crucial to stop harmful intruders such as mold and spider mites, so check your cannabis plants daily and keep the humidity low at 40 percent. Maintain the watering and feeding schedule established in week six.
As you enter week 6, the appearance of buds is even more apparent. A little defoliation doesn’t hurt now. Defoliation is the process of removing extra leaves to provide more light to the lower parts of the plant. Don’t overdo it, though, because the plant relies on the leaves to receive nutrients. Continue with nutrients meant for the vegetative stage as the plant will shoot up vertically.
Ideally, the seeds should be soaked in a glass of water for at least 24 hours. Some growers use a nail file to scratch the seeds gently before soaking them. This ensures that the seeds soak in more water, but you shouldn’t attempt this if you’re a beginner.
Week 5 begins with the plants producing lush leaves with a few buds appearing slowly. Continue with the “Grow” nutrients even at this stage lest you want the plants to stop growing vertically. This is the stage where an explosion of growth occurs and you need to support it with nitrogen. Using more phosphorous or potassium at this point will force the plant to focus more on the buds rather than growing.
Week 4 to Week 6
The seeds can be transferred to the soil at this point. It may take another day or two for the seeds to emerge from the soil and break their hull. Be patient and stop messing with the plants. You might be tempted to assist the seedling since it looks so fragile, but it will do fine without you. Also, remember to regulate the pH as it’s very important.
You can kill the plants faster by overwatering them. Not a myth; it’s a fact. So, go easy on watering. And, make sure that you supply enough water to keep the soil moist. Moist, not dripping wet or dry. As the process of photosynthesis goes on, new sets of leaves will appear.
The seeds can then be transferred to a wet paper towel and stored in a zip-lock plastic bag. Within 1-2 days, the tap root emerges and the seeds are ready to be planted. Note that many growers simply stick their seeds in the soil, and you can follow the same route if you prefer.
If you’re using a brand that has two parts of Growth and Bloom fertilizers, use only the “Grow” part during week 4. Most brands of fertilizers provide the numbering of N-P-K to make it easy for you. For example, if you’re using Floraseries from General Hydroponics, only FloraGro and FloraMicro (micronutrients) should be used during this stage.

The pH value of your soil will determine how well your plants can access the nutrients within. If the pH becomes too high (alkaline) or too low (acidic), nutrient lockout will occur and deficiencies will set in. Cannabis plants thrive in a soil pH of between 6.0 and 6.5. Use a pH tester to track pH throughout your grow.
AUTOFLOWERING GROW GUIDE: HOW TO GROW AUTOFLOWERS WEEK BY WEEK
Autoflowering cannabis plants are hardy, fast, and easy to cultivate in confined spaces. What’s not to love? Learn how to grow them week by week below.
Many growers elect to cultivate autoflowers because of their speedy growing rate. Their hardy genetics and forgiving nature also make them easier to grow and therefore more beginner-friendly.
Autoflowering strains typically move from seed to harvest in 8–10 weeks. However, some varieties can take up to 12 weeks to fully mature. Strains such as Bubble Kush Automatic and Quick One fall towards the faster end of the spectrum, whereas varieties like Royal Creamatic and Royal Haze Automatic take a few more weeks to ready their buds for harvest.
8 weeks, with subsequent weekly harvests when growing fast strains.
