- The plants are either crispy from overfertilization or there is mildew going on.
There are a lot of plants growing around it, impeding airflow. Also, there are weeds growing, which may be giving off poisons in their competition for space with the cannabis plant.
- Dropping temperatures
These naturally lock out nutrients by stopping nutrient absorption during the night time. The plants are thrown back on the nutrients that are stored in the leaves.
- Osmocote?
Osmocote is a fertilizer for ornamental flowers.
a) You should really use cannabis specific nutrients and media if you're starting out and...
b) Make a supersoil and make your own liquid fertilizer from plant parts through fermentation with sugar. (Take an old clean alcohol bottle, fill with sugar for 10% and 20% cannabis tops/leaves or flowers, fill with tapwater, airtight, and put in a dark place for at least 2 weeks.) This creates complete fertilizers of solid (slow) and liquid (fast) nutrients, so your plants are fed all the time.
Think of this as microbe-released rather than time-released.
Also, the taste of organic is much better than synthetics. And you don't have to worry about additives or chemicals. Even if you grow commercially, most people prefer smoking clean burning weed, which organics pretty much guarantees if you use ingredients that have no strong taste.
Fungi disease can be caused by bacteria, fungus, and nematodes. Leaf spots can be caused by cold water that is sprayed on plants while the plant is under the hot sun or HID lights, or temperature stress can cause them to show quicker than if these are not exposed to the plant.
