A lot of strains do that so don't start throwing things at it now or you could mess things up.
They're looking great so I'd just keep on keeping on at this point.

It's pretty common and usually not something to worry about. If the stalks are purpling there's a good chance they have some uptake issues, and my guess would be because the roots are cold. Apparently this happens more with LEDs too.
They look happy to me.

I have 3 different strains in one Tent right now and one has very red stems. There asleep or I'd send a pic. I've found that more times than not it's genetics. I've never had it screw up a plant. I started growing in the black soil of Iowa when I was 15, in 1975. Your good.

It looks fine. Mine did that too and had great smoke and harvests. Its usually from the LED lights. Its like how our skin pigmentation changes to protect from the sun. Especially people living near the equator. Sometimes you can notice the tops of the stems are reddish purple and underneath its still green. Also can be related to the strain genetics too.

Turns out it's in the genetics of Vushnu Kush. It's drying right now. I'm guessing 4oz harvest being conservative.

I wouldn't worry. Me nepali has red/purple petioles and the chemdog beside it doesn't. As long as their looking happy I wouldn't stress
The newer leaves start with green petioles, but as they inch out the portion in the light turns purple. It's cool to watch.
I can flip the leaves over and the bottom will turn purple to match. I have noticed the bluer the spectrum, the more the purple/Red comes out. This board is all 4000k with 16x660nm and four 410nm diodes. My other warm 3500k board doesn't seem to trigger the same strains as much. This could be complete speculation though.

Beside genetics , I believe I have read it can be a reaction to UV light exposure, not necessarily a bad thing as long as everything looks good-

I've noticed the distinct suntan lines when removing painters tape from stems.
The difference is stark
If I can find a pic I'll add it but the area under the tape is the "original" green color and the areas not covered by the tape turned purple over time.

Yes my Purple Kush is in the same tent as my Vushnu Kush but only the Vishnu has some red stems.

It can be and often is just genetics, it could also be a mg deficiency but they look fine; keep up the good work.

I growing Zowahh strain, started under LED'S (full spectrum, for veg and flower) cos it has more blue light than ordinary hps. After a week I separated plants, half of them in the tent under HPS another half stayed under LED'S. I've noticed that stems turned purple in the beginning. Under HPS plant colour back to normal green with minor purple colour. Under LED'S turned even more purple....So what does the LED'S actually do to the plant? I keep 24/28c° RH 60/70 PH 6.0 I thought lights to intense so turned down to the minimum but after few days no difference...Zowahh its a purple strain,I thought that's genetics plying role,but now I see the difference....
