I can't quite tell because of the quality of the pictures, but if what I'm reading is right.. Purple on the stem, it could be a nutrients deficiency.

Cold will often bring out colours. I wouldn't worry about it.

Phosphorus is a component of certain enzymes and proteins, adenosine triphosphate (ATP), ribonucleic acids (RNA), deoxyribonucleic acids (DNA) and phytin. ATP is involved in various energy transfer reactions, and RNA and DNA are components of genetic information.
Phosphorus (P) deficiency
Figure 11 is severe phosphorus (P) deficiency during flowering. Fan leaves are dark green or red/purple, and may turn yellow. Leaves may curl under, go brown and die. Small-formed buds are another main symptom.
Phosphorus deficiencies exhibit slow growing, weak and stunted plants with dark green or purple pigmentation in older leaves and stems.
Some deficiency during flowering is normal, but too much shouldn't be tolerated. Red petioles and stems are a normal, genetic characteristic for many varieties, plus it can also be a co-symptom of N, K, and Mg-deficiencies, so red stems are not a foolproof sign of P-deficiency. Too much P can lead to iron deficiency.
Purpling: accumulation of anthocyanin pigments; causes an overall dark green color with a purple, red, or blue tint, and is the common sign of phosphate deficiency. Some plant species and varieties respond to phosphate deficiency by yellowing instead of purpling. Purpling is natural to some healthy ornamentals

purple is not what you should be worried about i seen entire plants go purple from a mix of cold water and prolonged darkness and it was a purple strain .... which you might have but for example in my grow there are purple fan leaf stems and purple streaks up the big stems ill post it for ya dont know if ya can see it or not. also are you feeding them nutrients? if so back off cause your leaves look droopy usually a sign of deficiency. cheers bro

from what i can see just a few of his stems are purple , not gonna be from a deficiency ive never seen purple from deficiency just cold and darkness or strain related.
the pics r not that good but it is 82 in the grow box so i didnt think it was to cold. i cant seem to get a great pic of this but it is redish purple speckles on the bigger fuller plant the tall slinder plant has a dark purple streak down the branch to the leaf. all growning in my grow box ...

PH is too high I bet
That leeds to Nutrition lock out. Go buy a real PH meter for water and when watering; water with 6.0 PH and at the end of watering catch the run off with a mug and measure the Ph at runoff. You want to be under 6.25 through out. The last week of flowering you can let it raise to 7ph to sweeten it up. Not longer then that or she will get metal and calcium deficient and start to shrink.
