Hello bonitin,no there was no storm lately.But there is a lot of humidity late at night until early in the morning until the sun rise.
Hello drdawg,i dont know if i have updated my location correct.I live in Cyprus,i think this does not help you much about the conditions the plants grow.So i will try to give you as more informations i can.Yes,the plants have new healthy growth.The new leaves are green and have NO black spots on them.Most spots appeared i think in March.We have hot summers here (about 35-40 degrees Celsius,calm winters) and i water them every 5-7 days when the soil get completly dry,about 2-3 liters of water.The plants grow outdoors.Could this spots appear because of high humidity early in the morning and when the sun rise the plant gets burned???I will attach a photo that i belive a black line is caused from a water drop but i am not sure.I would like your opinion.If you need better photos from the entire plant(s) please let me know.
Thank you for your answers!!!
