Hi again mate! :hi
Being Cream Caramel an offspring of Blue Black, Mapple Leaf Indica and White Rhino, she has the genes of Blue Black (Blueberry x Black Domina) and so she can show this color... specially when submited to cold temps. It doesn't mean all Cream Caramel will have purple tones, but some of them end up with some beautiful blue or purple flowers. Maybe you are growing them outdoors and the difference between the temperature during the day and during the night is a big difference and it stimulates plants to get this kind of colours that are present in their genes.
Hope they are doing well, keep it sweet!
