indica V.S. sativa

cold weather huh?! cause i was wondering about the purple leaf stems too. do you think its going to make the buds purple maybe?

I think some deficiency's will also cause purple stems.

i know theres no deficiency tho, they are dark green getting all the nutes they need and ive never overfed. maybe its just a charectaristic of the strain.. just a bagseed from some really good dank
