Timing is importantĭifferent fertilizers work better at different times in the plant’s life cycle.Īt the very beginning of the sprouting stage, you probably won’t need any strong fertilizers and can probably just get away with using peat plugs or potting soil.
Although these help with specific processes inside the plant, they are not quite as vital as the three core nutrients. There are also micronutrients such as calcium, sulfur, magnesium, and many more. NPK aren’t the only nutrients found in fertilizers, however. This tells you exactly how much of each element is in that particular marijuana fertilizer. In fact, on most commercial fertilizers, you’re going to see an NPK ratio listed on the bag (e.g., 20-20-20).
These are represented by their elemental symbols of N, P, and K respectively.

When marijuana plants are grown indoors, they do not handle full strength dosages well, and it could cause the leaves to droop due to shock. If you are growing indoors, you’ll want to dilute this formula to one-quarter or one-half strength. Once your plant starts developing leaves, you will need to give it a 20% balance of phosphorus, potassium, and nitrogen. But as the plants grow, they will need additional nutrients. Potting soils are already mixed with these three elements which will aid the plant for up to three weeks. Nitrogen is important for leaf growth while phosphorus aids in bud growth. You will often see these values displayed on packaging as NPK. Healthy marijuana plants require three elements for firm roots and vibrant flowers with high yields: Nitrogen (N), Phosphorus (P) and Potassium (K).
Of course, you can always make your own nutrients with your preferred mixture, but usually it is much simpler to buy pre-made nutrients.
