Purpling color in my plants

I have noticed that the stems of the fan leafs are turning a purplish color on the top side and moving down the stem itself ,more or less with striped purpling. They are into the 3rd week of flowering. I have them set in organic Promix and have been watering with light doses of Pure Blend Pro Bloom 1-4-5
What I have for lighting are 4 Noma full spectrum led grow bulbs. The plants themselves look great. I do not know the strain as they were grown from random seeds. Should this be a cause for worry? Thanks

I'll be that guy and say it.....pics are always the best way to go when asking if everything is ok with your plants. Can't help you if we can't see what's going on.

what's your temps and water source and what ph/ppm or EC are you feeding

purpling in stems is usally low temps or more likely the first sign of nutrient deficiency

If the plants appear healthy, you likely just scored some purple genetics. Watch 'em but otherwise keep on growin'

I finally got a chance to take a few pics. They are not the best quality but you should be able to see what the problem is . I think it's more like a reddish purple. As you can see apart from that the plants look pretty good.

It could be the start of a phosphorus deficiency, maybe give them a full dose of bloom next time? could be mg too. promix alone doesn't have nutes in it so you have to be sure to provide everything

I was worried about this too. See pictures of my mother with red/purple stalks/leaf stems and the results in flower. If you have a couple of cool nights, the next think you'll see is coloring of the leaves. Leaf stems may turn blood red as well.

Your plants look perfect. If you start to see other signs of deficiency, you may have to take action. Otherwise, keep doing what you're doing.

I think people overreact to purple or red stems. If the plant is healthy then just ignore them. More often than not it's due to genetics and with the way so many strains are crosses of crosses of crosses there's dozens of strains in the genetic lineage. Many of them have purple stems. If you're not seeing any other signs that the plant is having issues just smoke a bowl and let the plants grow.
