Bud blight is a withering condition that attacks cannabis’ flowering buds. The pathogens causes brown, water-soaked spots on buds or chlorotic areas on stems. Buds eventually rot producing a gray-brown mass of spores; infections start within buds. Botrytis cankers develop to the point of limb breakage or stem splitting, especially if plant canopies are dense and heavy. Small, black sclerotia can develop within stem tissues. Like the buds, cankers produce gray-brown masses of spores. Seedlings can also be killed.
