What is wrong with my pepper plants? Some of them are showing deformations on young leaves. See this picture: Some of them are showing small holes or cracks, usually with brown edges. Some have irregular shapes, not the typical pepper leaf shape. I can not find any signs of pests, except that I had a very minor case of aphids (less than 20 insects per plant) in the past two weeks. They are 99% gone now. Is this damage caused by them?
I'm watering once every 1-3 days depending on temperature. The plants are in pots outside on my south/west facing balcony. I'm using 3g/liter of FloraSelf Tomato Fertilizer:
(N) 6 % (P2O5) 5 % (K2O) 9 % (B) 0,01 % (Cu) 0,002 % (Fe) 0,02 % (Mn) 0,01 % (Mo) 0,001 % (Zn) 0,002 %
