On the image you highlight 2 zones (both v and vi). If as in the senario mentioned you placed the leaves at zone v and the roses on zone vi. In my calculations to get the image that you have, only a major change in light conditions to the Zone v leaves could have caused the 'blow out' that you have. The leaves should have become a zone iii.5 with the red filter(Darker than original placement). Was there a change in light?
