Vierlana

Hi SHS, I've grown this strain this year, 7 weeks in today. Out of the 3 seeds I started with I only have 2 left and one of those is stunted, the last good one I have isn't massive but has some decent buds, out of all the CBD seeds I read that these aren't an easy grow. I just wondered what you soil mix is and maybe that will help me. I think they are really temperamental in the 1st 3 weeks of life.
