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.
looks like leaf miners they live inside the leaf ,copied from net To effectively rid plants of leaf miners with pesticide, in the early spring, place a few infected leaves in a ziplock bag and check the bag daily. When you see small black flies in the bag (which will be the leaf miner larva becoming adults), spray the plants daily for a week
