This article discusses how flushing a cannabis plant helps to remove excess nutrients and provides a fresh start. Flushing can help to counter nutrient lockout or before harvest, and if plants are left unchecked, nutrient burn can cause leaves to die completely and fall off the plant. – Flushing removes leftover nutrient buildup and excess salt from the plant. The process of flushing cannabis removes nutrients from the roots and soil, giving your plants a chance to absorb fresh nutrients and salts during the flowering cycle. When done correctly, flushing cannabis removes any excessive accumulation of minerals or salts that may be in the growing medium. This allows for a more balanced diet for the cannabis plant, preventing nutrient burn or lockout. After flushing marijuana, it is important to allow some time before harvesting your plants so they can absorb essential nutrients needed in order to grow healthy buds.

Flushing marijuana helps remove any excess nutrients that are left in the soil from fertilizers which can be toxic to your plants. It is important to level your plants by flushing cannabis a few days before harvesting because it will restrain the plants from taking in any more nutrients and restrict what is already in the soil.
For soil growers, flushing is recommended two weeks before harvesting and for hydro growers, it is recommended one week before. The most common recommendation is to flush your plants with straight pHed water. As a result of this, many growers nowadays choose to flush their plants two weeks before harvesting for the best results. For fertilizer companies who are using lots of nutrients, we would recommend flushing them for a couple of weeks for good results.

Flushing your plants is a process that involves watering your plants with three times the volume of the container for a day or two. This occurs when nutrient lockout occurs due to excess build up in the plants’ growing medium. Nutrient lockout can be prevented by adding nutrients to your growing medium at least once a week and then flushing it with three times its volume of water every other day. This will help prevent any nutrient lock and keep your plants healthy and thriving.
Flushing your plants is an essential step in the growing process, as flushing excess amounts of nutrients from the soil can counter nutrient lockout and help you notice any nutrient burn. If you do end up noticing a nutrient burn, you will need to cut out any affected foliage by hand. Once this has been done, it is important to flush with plain pH balanced water for several days in order to flush out all of the excess nutrients and help prevent further nutrient lock.
Nutrient burn can be caused by feeding wrong fertiliser or too much fertiliser, meaning plants need different nutrients. If the nutrients are not given at the right time and in the correct amounts it can cause leaves to turn yellow and cause inferior buds that may reduce yields and potency. This is especially true for cannabis plants during flowering stages as incorrect formation of buds can reduce yields.
Tried and experienced most experienced cultivators have experience first hand the importance of storing your plants with the correct nutrients, salts and other compounds to prevent toxicity. Once harvest time comes around, the plant will usually start to turn yellow or brown in its leaves – a hand glaring difference when compared to healthy plants. Store excess amounts of these fertilizers for your next growing cycle as it could easily make or break your yield
