@dyzzyppyxy no,i have not damaged mechanically the plant.Its the same black spots in a straight line and made the photo from a bigger distance.Yes,there is a lot of healthy foliage and it looks like its just aesthetical issue for now but this plants are something new for me and i dont want to get in bigger trouble.For sure its better to see your plants grow as healthy as possible.
@drdawg as i know there are a lot of aloe vera species so it doesent surprise me that your aloe vera look different.Just google "aloe vera species" and you will get even more confused
About the climate you are correct.No frost,snow or very low temperatures during winter at my location.Dry,hot summers with a lot of humidity during night until sun rise.Thats the only explanation i have about the straight line for now.That could be a water drop from the humidity (if humidity affects somehow this plants).
