Thank you so much for the tip..I also did the water and liquid soap+the oil .. but the plants were already damaged from the beginning because part of the newbie plants were frozen due to minus temperatures in April... As for the molds, I used the soda water spray I got rid of the molds but the aphids came back..but I will be careful in the beginning of planting next Spring ...thank you for your suggestions and for visiting.Have a good day!
