Try setting org-edit-src-content-indentation to 0. I'm not sure that
it is going to work, but (based on rather flimsy numerological evidence,
namely that its default value is 2 as is the indent below) it might.

BTW, I don't get this behavior but I don't use f90 mode, so I'm not sure
whether there is some setup I'm missing. I get (with
org-edit-src-content-indentation set to 0):

  #+BEGIN_SRC f90 :results verbatim :exports both
  program main ! This is a very very very very very very very very very
  very very very very very very very long comment line.  print *,
  "Hello, World!"  end program main
  #+END_SRC
