Plant Changing Colors Overnight

Ok so i had my plants outdoors until now, I recently hit them with 125W of CFL's on a 12on 12 off cycle. I went to check them this morning (about a week in) and there is this weird pink or purple color emerging between the leaves and at the top of the top leaves. Is it budding, or is there something wrong here? I'll get pics up soon

.


I'll get a closeup later, but as you can see this purplish tint is weird

since you are now on 12/12 they have a dark period, and it gets cooler during the dark period which brings out purple colors if any in the strain. no worries.

red/purple stems/petioles can be quite normal as certain strains mature but can also be caused by low temps especially night time temp or a slight phosphorous def. but nothing to worry about.

Londoner is a-1 on the info , warm it up and check ph of dirt or wateva ur usin under 4 ph will make a purple plant that taste like shit
