Purple Stem??

This is my clone from an unknown strain, with a dark purple stem that turns green at the very tip. Is this some sort of deficiency that i should be worried about?

hm.. a mother plant of trainwreck that was recently given to me has purple stems... looks pretty much just like that... he says its supposed to be that way... and mine seems to be fine...

Purple stems seems to be pretty normal in my cloning experience (which is admittedly limited).

Dont worry Its perfectly normal

I was actually wondering the same exact thing since one of my plants is like that as well.

Thank you guys for the fast respose.Much Thanks
