Types of nutrients for autoflowers

There are three main types of nutrients that autoflowers need in order to grow and produce buds: nitrogen, phosphorus, and potassium. These are often referred to as the “big three” nutrients. In addition to these, autoflowers also need smaller amounts of other elements such as calcium, magnesium, and sulfur.

Autoflowers are a type of cannabis that is genetically programmed to flower automatically, regardless of the photoperiod. This makes them a popular choice for growers who want to avoid the hassle of having to change the light cycle in order to induce flowering.

Advanced Nutrients for Autoflowers

There are many different autoflower strains available, each with its own unique set of genetics and growing requirements. However, all autoflowers share one common trait: they all need a nutrient-rich environment in order to thrive.

When growing autoflowers, it is important to use a nutrient system that is specifically designed for them. This will ensure that your plants get all the nutrients they need in the right proportions. Many general-purpose cannabis nutrient systems will work fine for autoflowers, but there are also some that are specifically tailored for this purpose.

When to start feeding your autoflowering cannabis plant?

As a general rule of thumb, you should start feeding your autos when they are in the vegetative stage. However, this can vary depending on the strain and grower. Some growers like to wait until their autoflowering strains are in the seedling stage, while others wait until they are in flower.

The best way to determine when to start feeding your autoflower plant is to consult a feed schedule. There are many different schedules available, so be sure to choose one that is suitable for your particular strain and growing conditions. You should also be aware of the potential for nutrient burn, so start with a low dose and increase gradually as needed.

Best autoflowering cannabis feeding schedule

The best autoflower feeding schedule is one that provides the right amount of nutrients for the plant at each stage of growth. Autoflowers are different from other cannabis plants in that they do not need a change in light cycle to flower.

This means that growers can keep them on a vegetative schedule for their entire life cycle. However, it is still important to provide the right nutrients at each stage of growth. The best way to do this is to use a feed schedule designed specifically for autoflowers. This feeding schedule will ensure that your plants get the right amount of nutrients at each stage of growth and avoid nutrient burn.

This is a simple feeding schedule that I follow when feeding nutrients to autoflowers. Around week 5 of flowering, flush your autoflowering cannabis plants remove any excess nutrients or salts. This prevents issues as well as preventing your buds from tasting too “nutty”. Always follow manufacturer feed charts as a baseline of calculating for this feeding schedule.

What’s the best Autoflowering Nutrient Feeding Schedule?

Week 3: ½ strength veg. nutes + Root growth enhancer + Floralicious Plus Foliar Feed

Week 4: Full strength veg. nutes + Root growth enhancer + Floralicious Plus Foliar Feed

Week 5: Pre-flowering – ½ strength veg. nutes + ¼ strength bloom + Root growth enhancer

Week 6: Full strength bloom nutes

Week 7: Full strength bloom nutes

Week 8: Full strength bloom nutes

Week 9: Full strength bloom nutes

Week 10: Ripening – ¾ strength bloom nutes

*Add foliar feeding 2x/week of Floralicious Plus to increase growth rate and improve overall plant health.

Auto Seedling Phase

Reduce the recommended dose to 1/8 strength and feed every other watering until the 2nd set of true leaves have fully developed. Feed a Mycorrhizae, root growth enhancer, or other beneficial microbes to increase root growth and production

DO NOT OVERWATER.

Allow for some dryback if growing in a substrate (soil, coco, rockwool).

If growing from autoflower seed in hydroponics, maintain pH between 5.8 and 6.4, 1/8 nutrient solution.

Increase to 3/4 to full strength veg nutes after 2nd set of true leaves are fully developed for roughly 1 week.

Auto Veg/Pre-flower Stage

Since vegetative growth stage for ruderalis cannabis plants doesn’t truly happen, we are looking for a nutrient that contains an NPK ratio similar to 2-1-1. An example might be a nutrient (veg, flower, micro, whatever the manufacturer might label it as) with NPK 20-10-10 or 10-5-5.

Auto Flowering Stage

One pre-flowers have started as each lighted node (tops or branches that the light reaches without shade) begin to feed flowering formula at full strength.

*Always pay close attention to what your plants are telling you, they may want more or less food at any given stage. Always be careful of nutrient burn and overwatering. Autoflower growers know that any lost day with an issue with overwatering, overfeeding, or pests can diminish yield. No one wants the yield of the damaged autoflower plant.

Autoflowering Nutrient Tips

Autoflowering plants are a great option for growers who want to maximize their yields. These plants have a shorter life cycle and can be grown with less attention than traditional cannabis strains. However, autoflowers still need to be properly fed in order to reach their full potential. Here are some tips on how to best feed your autoflowers:

  • High-quality nutrients: Autoflowers are especially sensitive to nutrients, so it’s important to use a fertilizer that is specifically designed for them.
  • Observe and Adapt Feed: Overfeeding can lead to nutrient burn, which can damage your plants. Make sure to follow the recommended feeding schedule for your particular strain.
  • Hydroponics: Autoflowers are particularly susceptible to root problems when grown in hydroponic systems. If you’re using hydroponics, be sure to monitor your plants: check pH, light leaks, reservoir water temperature, and reservoir PPM/EC often.

By following these tips, you can ensure that your auto cannabis plants get the nutrients they need to thrive and produce large, healthy flowers.

Feed Schedule and Nutrients for Autoflowers FAQs

When should I give my Autoflower nutrients?

Start feeding your Autoflower once it has germinated and opened from the seed at ½ strength. This is a risk. However, adding organic nutrients and/or root stimulators this early carries much less risk of burning and killing your seedling.
