For a Cannabis plant to grow to its full potential, there is a number of different elements it must consume during its life cycle. Phosphorus, is used throughout a cannabis plants life cycle, but more is needed during the flowering period.

Finding the right balance, of what to feed your plant and when, can be a difficult task. This guide will help you keep things balanced, and also fix any problems that may arise.

How a Cannabis Plant Uses Phosphorus

Phosphorus is the "P" in N/P/K Ratio. Like Nitrogen and Potassium, it is a "Macro nutrient". In other words, it is one of the three main elements needed in plant growth.

"P" is like a power line, and it connects all of your plants cells together. The energy created by photosynthesis, is then transported around the plant using phosphorus.

Flowers are also built out of Phosphorus, which is why you will find bloom foods, and P/K boosters will be high in phosphorus.

Phosphates can be difficult for a plant to break down and consume. But, the root tips will form a symbiotic relationship with the bacteria and fungi in your medium. The plant will give them sugar, and in turn, they will break down the big phosphates, so it is more accessible to the plant.

Phosphorus Deficiency

If a plant is lacking in "P" it will display these symptoms:

In order to grow happily, and heathliy, Plants need a large amount of phosphorus, especially during the flowering period. Without the correct level, your plant will suffer symptoms such as, small leaves, or they may also have a blue-green colour.

Stems and branches will also turn purple if your plant is suffering a phosphorus deficiency.

The deciency will start to show, firstly, in the lower leaves of the plant, and then make its way up the plant. In extreme cases, your leaves will either develop purple or black blotches, and fall off.

A cannabis plant, uses phosphorus to build buds, and also to keep the plant well energised. A deficiency will reduce the rate of bud growth, and will cause you to lose out on final yield. Make sure you get the best harvest possible, keep your levels in check.

Phosphorus Excess

If your plant has eaten too much P, it will display the symptoms:

"P" excess will display itself in many ways. The excess will show itself as Iron, Zinc, or even a cal/mag deficiency. This is because too much phosphorus will damage the tips of your roots, and your plant will not be able to eat properly.

Also, if you burn these tips, your plant will not be able to work in conjunction with the microbes. This will effect your plants intake of nutrients, which will cause it to suffer with many problems.

If issues arise, it will depend on the medium and what foods the plants are eating. But these problems are easily fixable. Just remember, when feeding your plant:  It is easier to fix an under fed plant, than it is to fix an overfed plant.
