fiddyonefiddy Reviewed by fiddyonefiddy on . purple lines up stem hey guys ... just curious .. im pretty sure this isnt a mineral deficency of any sort as the the plant is in a wholly prefect state , perfect colour through out the folage ,, a really nice dense green ,, but i have 4 purple lines that start at the base of the plant and proceed all the way up to the apical bud, it loooks unreal and it has beeen there since it started from seedling ... i was wondering if any body had any idea about what x species of cannabis this is ,, its very strong smelling Rating: 5
