At this stage, you must be very careful not to overfeed. You can start your autoflower with 1/8 of the recommended nutrients or better yet, just give the plant water for that first couple of weeks. If you overfeed your plant at this stage of growth it is highly possible that the baby plant won’t survive or if it manages to survive then the overall yield of the damaged autoflower will be greatly diminished.
When the first pre-flowers start to appear you need to change your feeding to a mix of half vegetative and half blooming nutrients. You need to slowly start introducing more Phosphorus (P) and Potassium (K).
Because you’re not feeding the plant directly, she can decide when and which nutrients to absorb so unless you do it on purpose, it’s really hard to have problems related to an excess or lack of nutrients.
Tip: Always read the recommendations as amended mediums contain different amounts of nutrients. Some may have the amount needed for the first weeks but others can have the amount needed up to the pre-flowering stage.
Slow-release nutrients can come in pellets or in powder form. Usually used as a top dressing or pre-mixed with soil, this is the simplest way of feeding because it slowly releases nutrients when watering. So you don’t have to worry about feeding your plant until harvest unless you see any signs of deficiency.
No matter what the percentage of the other nutrients is, just make sure that Nitrogen (N) is available more than those other two elements. Autoflower cannabis also needs those secondary nutrients but commercial fertilizers usually have a mix of the other nutrients your plant needs in the solution.
Both macro and micronutrients are delivered by watering with mixed nutrients, pre-amended soil, or slow release powder.
When we see that our autoflower plant starts to grow fast we need to start giving it more nutrients. Usually, it is best to give half of the recommended dose of nutrients, but if the plant gets really bushy you can give it a full dose.
Some growers believe that the time when the little seedling gets its true set of leaves until it starts flowering is the vegetative growth stage for autoflowers. But it really doesn’t matter how we call this stage because we need to feed it just like a regular photo-sensitive plant in its vegetative stage.
All autoflowering cannabis plants, like any other plant, need nutrients to stay alive and grow. Plant nutrients are divided in Macro and Micro. Macronutrients a
Autoflowering cannabis tends to be at its healthiest when given just the right amount of nutrients. In some cases, plants can go through the entire seedling and veg phases without any supplemental nutes, as most soil mixes already contain enough macronutrients and micronutrients to support these phases of growth.
Don’t top, prune, or pinch your autoflowers like you might do when growing conventional cannabis. With autoflowers, the only training method you should use is low-stress training (LST), where you carefully bend and tie down your plants so all bud sites are equally exposed to light. When performing LST on autoflowers, just stick with bending and skip the part where you’d top your plants. If you plan to do LST with your autoflowers as an alternative to a SOG, ensure that you start soon, but be gentle to avoid breaking your plants.
To carry out a SOG with autoflowers, you’d simply plant your seeds directly into even smaller containers that allow you to fit as many plants as possible into every square metre of space. How many plants you want to use for your SOG, as well as their exact pot size, will depend on the space you have available. This may also vary from strain to strain. Feel free to experiment to find the ideal pot size and number of plants that produces the best yields in your indoor grow space.
How do you water cannabis properly? For starters, don’t water your plants on a fixed schedule, but instead only when they need it. You should always allow the soil to dry out between waterings. A good way to check if your plants need water is to lift up the pots. You should have a pretty good idea of how light a dry pot is compared to one saturated with water. As such, only water when the pot is light and the soil has dried out. Overwatering can be deadly, so it’s better to err on the side of caution.
Many cannabis growers overfeed their cannabis plants. This isn’t too surprising, seeing that makers of cannabis nutrients want us to believe our plants require constant supplementation to survive and thrive. Nothing could be further from the truth.
You can also grow your cannabis in organic soil. This will ensure your plants have everything they need for healthy growth all the way to harvest, and you won’t ever need to administer additional nutrients! Some growers make their own organic super soils, which are perfect for growing autoflowers. That being said, it’s important the soil is not too “hot” given the sensitivity of these cultivars.
You also need to watch the temperature in your grow room. Cannabis does best at a moderately warm room temperature of 20–25°C. Any excess heat, but also cold spells or chilly nights, can stress your plants, slow their growth, and result in poorer yields.
When starting your seeds, and for young plants, you can also use standard fluorescent lamps such as T5 lights. These use very little energy and don’t get warm, so there is no risk of burning your sensitive seedlings.
More than anything else, genetics will play the biggest role in determining the final outcome of your grow operation. But what makes the right strain? Well, let’s start with your personal preferences, for example, what type of effect you want from your cannabis. If you’re smoking to get blazed with the best and the latest, you can’t go wrong with THC monsters like the super dank and potent Royal Cookies Automatic or Royal Gorilla Automatic, our automatic variants of two popular strains!
