here is my personal experience as i am new to growing but have tried various things, i have left flowers on the pods, and have pulled them off. and i have no tails on pods i have left flowers on and have a nice tail on a pod i pulled the flower off when the pod was a little round nub(no tail at that point) so i think its just mother nature that shapes pods not the flowers. the flowers will cause a narrow spot but it my experience that not enough to cause that type of shape. but this is my experience and i could be wrong.Almost half the pods on one of my Orange Habs looked like that. I believe its caused by the flower not falling restricting early pod growth.
