Thanks for the question.
Several possibilities.
- Bacterial – water soaked lesions, obvious streaming when look for. I don’t think this is the case here!
- Anthracnose (Colletetrichum sp). Spots tend to be sunken and can have a dried out appearance as it progresses. I don’t think this is the case here either!
- Physiological – excessive water. For whatever reason, anthracnose-like spots are observed when there is excessive moisture – typically happens when there is irregular watering (I know as that occurs often on my own aloes). Best bet here is to repot and let regrowth.
