Lollipop yellow leaves on auto??

I would recommend leaving all healthy leaves alone and only removing the yellow/yellowing leaves, as by the time they are yellow, they have served their purpose. Some thoughtful "lollipopping" of the lower and internal flower sites near the stem is OK too, this will also allow for better air circulation, which can help prevent moulds and fungus from developing once your flowers get big and chunky. Hope this helps.... Organoman.
