Brown Spots on Cannabis Leaves: Causes and What Helps
Brown spots on cannabis leaves can result from calcium or potassium deficiency, from excess fertilizer and salt in the root zone, or from leaf spot fungi. Where the spots appear on the plant, a yellow halo, and pH and EC readings help narrow down the cause.

Yellow Leaves on Cannabis: Telling the Causes Apart
When the lower leaves of a cannabis plant turn yellow, nitrogen or magnesium deficiency, overwatering, or leaf breakdown in late flowering are common explanations. The pattern of discoloration, pot weight and pH value narrow down the cause.

Bud Rot in Cannabis: How to Identify and Prevent Gray Mold on Buds
Gray mold caused by Botrytis cinerea destroys cannabis flowers and often starts inside dense buds before any sign shows on the surface. This article covers symptoms, the conditions that trigger infection, and evidence-based prevention indoors and outdoors.

When to Harvest Cannabis Trichomes: Colour and Maturity Signs
Trichome colour, moving from clear to cloudy to amber, and stigma colour are the main signs used to judge cannabis harvest timing. This article reviews what peer-reviewed studies say about reading these signs and why trichomes on the same flower mature unevenly.

Chemovars – Why the classification into Sativa and Indica is scientifically inaccurate
The terms Sativa and Indica are often used to describe the effects of cannabis. However, modern scientific research shows that this classification does not adequately reflect the actual genetic and chemical differences between cannabis strains. Instead, the term chemovar is gaining importance, as it describes the plant based on its cannabinoid and terpene profile.

The Biosynthesis of Cannabinoids
Cannabinoids such as THC, CBD, and CBG are produced in the cannabis plant through a series of biochemical reactions that primarily occur in the trichomes of the flowers. The starting point of this process is cannabigerolic acid (CBGA), from which various cannabinoid acids are formed through specific enzymes.

What are flavonoids?
Flavonoids are a group of secondary plant compounds that are also found in the cannabis plant. They contribute to the color, aroma, and possibly also to the biological effects of cannabis. Some specific flavonoids, such as cannflavin A and cannflavin B, are found almost exclusively in cannabis.

What are trichomes?
Trichomes are microscopic resin glands found on the surface of the cannabis plant. They produce the plant’s primary active compounds, including cannabinoids such as THC and CBD, as well as aromatic terpenes. They play a central role in the effects, aroma, and overall quality of cannabis.Where the cannabis community meets: forums, groups and other places to connect across the German-speaking world — what's there and who's behind it.
