Hi, I have a Echium in a large pot. I protected it from frost and it was coming along fine but it's beginning to look bad. The older leaves look chlorotic (new leaves are fine for a while) then develop brown spots which eventually cover the leaf which curls up and dies. The plant is in full sun in a sheltered location and is watered regularly. It was infested with aphids and I sprayed with Roseclear but there were brown spots on it before I sprayed. I include a few pictures. Thank you for your help.
