Hey growmie,
HERE ARE A FEW WAS TO TREAT LEAF SEPTORIA IN CANNABIS PLANTS:
1. REMOVE INFECTED FOLIAGE
The first step to effectively dealing with leaf septoria is removing infected leaves. If caught early, you can usually prevent the spread of the disease by simply removing all infected lower leaves and burning/destroying them. However, if the disease has spread to the height of your flowers, you’ll generally want to skip this step. Removing foliage from flowering areas will greatly weaken a plant and reduce the quality of its buds.
2. IMPROVE AIR CIRCULATION
Proper air circulation is extremely important for cannabis plants and plays a big role in the management of pests/diseases. If you’re growing indoors, improving air circulation can be as simple as adding an extra fan into your room and creating some space between your plants. If you’re working outdoors, however, this might be a bit more difficult. Pruning is also a great way to help create airflow in and among plants. Try trimming down extremely bushy areas of your plants and avoid having leaves touching or laying on top of each other.
3. AVOID MOISTURE
Moisture is another major player in the spread and germination of fungal spores. Hence, you’ll want to avoid moisture as much as possible. Avoid overhead watering as this will wet the leaves of your plants and consider watering slightly less regularly in order to give the soil a chance to really dry out. Also, water early in the day to allow the soil to dry out during daylight hours.
6. KEEP TRACK OF TEMPERATURE AND HUMIDITY
Remember that leaf septoria naturally strikes in hot, wet conditions. Hence, if you’re dealing with an infection, try driving down the humidity and temperature levels in your grow space (where possible).
HOPEFULLY, THIS WAS HELPFUL AND REMEMBER "HAPPY GROWING AND FREE YOUR MIND ONE PUFF AT A TIME".
