Growing 4 clones, Durban Poison and Chocolope. Growing in coco, perlite mix with my own compost. 10 gallon fabric bags. Advanced Nutriments PH Perfect Sensi Grow. Rain water. Feed once a week, water twice. All plants showing problem. Starts on leaves at the bottom and goes up.
No, no bite marks. Stems and stalks are fine. I'm going to put down some upside down masking tape on the pot around the stem to see if it captures anything.
