Hello ! I am growing just one plant for fun actually. Unfortunately from the first weeks the plant started to get some strange marks on every leaf as seen in the images. I do not believe i am overwatering it. I have the plant outside and the temperature is about 30-40c degrees lately. Could the heat be the problem ? I transplanted to larger pot . I used some home remedies for insects (green soap + garlic + alcohol) but it looks that this didnt help. I inspect almost daily the plant but i cannot see anything flying on it or any other kind of insect. Still i see new leafs after a few days again with the same marks.
