Purple stems?

[jonnylorenzo]

What does it mean if my stem is purplish color?

 

[Kindbud]

usually means a purple strain but also can be a diffencency

Most times PH is off...

If I remember right, purple stems cab be a phosphorus deficiency. It can also be from the temperatures getting too low at night.

However, many strains just have, naturally purple stems sometimes.

If the rest of the plant is in good condition, I would ignore the purple stems for now. JMO

[jonnylorenzo]

I was told not to use nutrients till I see sex signs

 

[Kindbud]

nope thats totally wrong it needs nutes that may be the reason for the purple steams

 

[jonnylorenzo]

[jonnylorenzo]

Sativa (purple stem)



I've noticed now that I didnt notice before is that the purple only really goes towards the top of the branches and fades toward the bottom...?

I believe you need to add some dolomite lime to your soil. The plant in the first pic is showing early signs of magnesium deficiency. You can get some good lime from the garden store. It is made by Espoma and it is really good for keeping the pH in the soil in proper balance as well as supplying both calcium and Magnesium in the proper amounts to serve your plants. If you cant find the Espoma any of the powdered or tiny grain dolomite lime will do, but don't get the Hydrated lime as that is almost always just calcium. You want Dolomite Lime.
