Is their anything wrong with my plant?

the stems on my plant are purple,is this bad?
Also the tips and sides on some of the leaves are turning light purple.plants in 1 week flower
And also the stems been purple for like 2 months

What's the strain ?, there's some strains that tend to turn purple during flowering. I've been told that purple stems is a sign of over fert, not sure if that's true.

i dnt know what strain just random seed but its sative for sure
