PhosphorusJanuary 8, 2019
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 fix any problems that may arise..
Phosphorus is the “P” in N/P/K Ratio. Like Nitrogen and Potassium, it is a “Macro nutrient”. This means it is one of the three main elements needed in plant growth.
“P” is like a power line, connecting all of your plants cells together. The energy created by photosynthesis, is 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. 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.
If a plant is lacking in “P” it will display these symptoms:
Plants need a large amount of phosphorus to grow, healthily and happily. Without the right level, leaves will be small and have a blue-green colour. Stems of the leaves may turn purple. Starting with older leaves first and moving onto the newer leaves in bad cases. In extreme cases, your leaves develop purple or black blotches, and fall off.
A cannabis plant, uses phosphorus to build buds. A deficiency will reduce the rate of your bud growth. To make sure you get the best harvest possible, keep your levels in check.
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. Too much phosphorus will damage the tips of your roots. Too much will burn these tips, and your plant will not be able to work in conjunction with the microbes. This will effect your plants intake of nutrients.
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.
