Stem and Leaves Turns Purple

I'm a little bit confused with this.

- Strain : AK-49
- Germinated on 17th of November
- 400W HPS (30 cm height from the top of the plant)
- it's still vegetative (18/6 cycle)

3-4 Days Ago, some of the stem turns to Purple, it looks like a stain, just purple dots.

and today, the stain goes to the leaves.. What's that mean?


- i need a really detailed answers, thanks

The First Picture is My plant 1 week old

The Second is 2 weeks (yesterday). you can see the purple stem.

today the leaves also turning

i dont see a problem, looks normal. by the way, 12-12 is flower not veg.

Stick that thing into 18/6 or 24/0 or some other max veg cycle...
and maybe less confusion....
Good Luck!

Plant looks perfectly normal. Stem looks healthy, leaves are good and setup is okay. Don't see the problem.

Yeah i'm sorry, i mean 18/6

btw, thanks for your answer !

Also mate, the purple stem can be genetic, nothing to do with your environment. I really wouldn't worry about it. Looks like a A-OK plant!

Goodjob so far!!

most seedlings get the little bit of purpling, regardless of genetics.

^^^^^^^^^^^^ Perfectly normal, even mature plants can have some purpling on the stems. Cooler temps can also play a role in purpling and some strains just carry that purpling trait.

The plant looks good to me,keep growing.
Could just be the strain.
