As a growers we like to take preventative measures rather than treating infection and disease. One of the biggest issues, especially for indoor growers is a fungal disease that almost no plant is immune, most growers call PM.
This is identified by seeing what looks like powdered sugar on the leaves and stem of your marijuana plants. The white powder is tiny spores that can spread in just a breeze.
Powdery Mildew is caused by a few things, the more likely reasons for powder mold are:
Sitting water: Whether it be on the leaves, soil cups or next to plants. Sitting water can cause many issues.
Stale air: Be sure there is a good air flow in your grow space. Enough to move the leaves, but not so much that the plant bends.
Bringing in previously infected plants from other grows.
Treating Powdery Mildew
At Cloud City Clones we use green clean to prevent mold, but this can also be used to treat PM. We have seen other organic ways to treat, such as:
- A tablespoon of baking soda
- 1/2 of a teaspoon of liquid soap (dawn is a good brand)
- 1 gallon of water (RO water if possible)
For the treatments to be effective, fungicides you do buy should contain lime-sulfur, sulfur, neem oil, and potassium bicarbonate.
There are harsher chemicals that should only be used as a drastic measure. Chemicals can leave residue for the remaining life span of your plants, into the buds. This can cause a bad taste, smell and sometimes health issues.
Remember, Powdery Mildew can kill your plants if left untreated. To save your grow, treat immediately.
