Here's a pretty little sunflower to color to help celebrate the end of summer and beginning of fall (and yes, i intentionally released it on exactly the fall equinox) Beware - this puzzle is challenging! A solution path has been posted as a hidden comment for those of you who are interested! Good luck!

The Rules:

1. [Antiknight] Normal sudoku rules apply - in addition, cells a knights move away from each other cannot have the same value.
   
2. [Killer] Numbers in cages all sum to the same total which must be deduced.
   
3. [Ambiguous Kropki] Each pair of cells separated by an orange dot are ambiguous kropki pairs, and must either have a difference of 1, or a 2:1 ratio, which must be determined by the solver.
