Purple is either a sign of Phosphorus or cold temps during the night cycle. I've never personally experience this so lets wait for someone with more know how then me. Otherwise it looks really healthy.

Do you add Dolomite to your soil?

can also be cause by a lockout to much Cal will lock out Mag

Good diagnosis! I just harvested a grip of plants with the same color on the edges and it was because of lower temps, Or a phosphorous situation. The Fox Farm open sesame made my colors more pronounced. It is very high in phosphorus. IMHO,..Nothing to worry about. Looking good!! ;-)
