the chloryphyll could be that of a purple strian and might just have triats of a plant similar to black dominica, black russian , black pearl and might have purple triats beyondthe purple color. i doubt its mold just a triat used for he plsnt thinking its in the last stages of flower and its trying to collect the last bits of lumens in flower. i wouldnt freak out. just let her finish as usual. understand the plant will continue to color up so dont be alarmed. the nuggs will continue to smell like fruit even in the finish of flower- prolly moreso.
hang on, let them ripen and chop when trikes turn 50% amber or more....you will ahve some KNOCK OUT smoke my friend.
