theres some sort of purple/gray mold growing on the truck and spreading to some branches and literally eating right through the main trunk! its killing one of my best girls!!! it has to stop today! i tried putting some rubbing alcohol on it to kill it and then some duct tape over it to stop the spread but now shes dying! i'm so sad this is happening to such a good lookin girl... why cruel world why... oh and btw its a blue dream outdoor veg about 15 weeks old just about to flower, if any of that helps..
Have you tried using baking soda water and spraying down the affected area heavily? This raises the ph so high that fungus can't survive. Although it does not work on all types.
