Signs of white powdery on cannabis 

It helps big time when you are in a position to fathom at the earliest moments that your grass plants are affected by powdery mildew on buds. If you set your eyes on wilted and mottled leaves in your marijuana plants at any given time, please take action. Also, if the leaves appear spotted, flour-like, and fuzzy, that could be a disaster in waiting.

Mildew spreads fast and can render your joy useless within minutes. That said, if you see some white patches on the weed leaves or buds, then that is undeniably mildew on marijuana. The condition can get rectified to the entirety if you happen to see it early. This explains why we mostly recommend that cannabis farmers accord their beauties the attention they deserve. 

It is important to note that mildew mostly affects the smallest cannabis plants on a farm before going for the vastest. If there is a somewhat damp scent in the garden, then it is essential to note that the buds have gotten affected.

The main cause for white powdery on marijuana 

Cannabis farmers who cultivate their plants in high humidity areas (specifically with more than 55% Relative Humidity) face mildew problems. Ventilation needs to get ensured in these places to strike a balance.

High humidity levels are, therefore, the leading cause of white powdery on cannabis.

Secondly, if one plants their strains in such a way that there is contact among different strains, then the highest chances are that mildew will develop and end up spreading across the entire farm. This means that spacing is crucial and should get done in such a way that no plant will end up touching the other's leaves, regardless of its size. Also, proper spacing means that should any plant be affected by white powdery, doing away with it or treating it gets easier.

Lastly, clones may cause mildew marijuana. Picture this: If you used a mildew-infested clone, then the highest chances are that the very clone will end up transferring mildew to the other neighboring strains.

As an adage goes, prevention is better than cure, which doesn't exclude mildew on marijuana. So, when possible, we would recommend that you take these precautionary measures before you may start looking for the best ways to eradicate white mildew from marijuana.

  1. Ensure that you have sufficient space before transplanting your ganja strains 

  2. Water the plants at the time when you get assured that after that, the plants will get sufficient lights, preferably more than 5 hours. Of course, this is irrespective of the light being natural or artificial. 

  3. Trim the fan leaves to ensure there is a continuous airflow between the leaves and the buds. Aeration helps in keeping skyrocketed humidity levels at bay.

Apple cider

If you catch it on time, you can get rid of Powdery Mildew. All you really need are some things you probably already have at home! You will need 2 or 3 tablespoons of apple cider vinegar that has 5% acetic acid and a gallon of water. Mix it together and spray it on your plants. You can even do this before you actually have a mildew problem as a way to prevent it. Take care not to use too much vinegar as it can burn plants. If your mildew problem has progressed quite far then using an apple cider vinegar concentration of higher than 5% may be needed.

A mixture of milk and water is another easy way to fight against Powdery Mildew. Weekly spray your plants (when they are going to have light for a few hours) with the mixture of 1 part milk to 9 parts water. The reason why this strange concoction works for mildew is that milk's protein reacts to sun and light and creates an antiseptic. You can increase the ratio of milk to water, but don't go overboard as it can have adverse side effects.
