Purpling stems are most commonly caused by the temperature being too hot, or too cold in your grow room.

If your in flowering and the stems are starting to turn purple, it is most likely a Phosphorus deficiency.

It could also just be genetic to the strain.

my stems are turning purpish resish and there in veg would it still be Phosphorus def

thanks for that vague nugget of not-so-useful information.

what else you got?

well if at any point during your grow you get browning leaves it could be overnuting, overwatering, or temperature burn.
or if your at the end of flowering it could be that the plant is using the last of its resources to finish fruiting.
just thought ide let you kno. hehe.

some stems go purple in veg, if they are dark purple-red its usually a defiency

Mine were green.. Then 3 days in a cooler climate they turned purple.

my plant also has purple/reddish stems, but the other 2 are nice green, all three are grown in the same conditions. Could this be because i topped it at 2 weeks from seed?

All the stems on my plants mother plant/clones/flowering are all purple now but then again they are Blueberry (DJ short) & many people say its down to the genetics on this specific strain. Any input on this?
