We recommend these organic fertilizers:
Cannabis plants need different amounts of these nutrients throughout the different stages of growth: more nitrogen during vegetative growth, and more phosphorus and potassium during flower for bud production—also called “bloom” nutrients.
Your marijuana plants need the following primary nutrients, collectively known as macronutrients:
Disadvantages of organic nutrients for cannabis plants
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.
Calcium is responsible for keeping the structure of cell walls in a plant together. Without calcium, new growth won’t develop properly and the plant won’t function as it should. New growth will be stunted, leaves will curl, and rusty spots will show up on the plant.
There are some complications in working with organic fertilizers. The main issue is if your weed plants have a nutrient deficiency, it takes longer for a plant to absorb organic powder nutrients, which can increase the damage to plants. Liquid nutrients act much quicker. Other disadvantages:
When creating a first batch of tea, keep the solution simple. If you use city water, allow it to sit and breathe so chlorine can break down. Once your tea is brewing, keep it out of direct sunlight and make sure the air pump is running and oxygen is being pushed through the water.
With marijuana plants, you get what you put into it. If you don’t put a lot of effort into your grow, most of the time your plant won’t reward you with a lot of yield.
Answer: Possible? Yes.
Question: Is it possible to grow marijuana without nutrients? Or to grow without proper soil, for example using dirt you dig up outside?
The best thing you can do at this stage is to arm yourself with lots of knowledge. As you learn more about what works and doesn’t work, you’ll learn about all the ways you can save money while growing and still get outstanding yields.
