First Grow Jack Herer

Jack (feels odd calling a girl Jack!) has been growing well but not without raising some concerns. The leaves are a coming out mottled and some have started to curl a little at the edges and I'm not sure what's causing it. One thought I had was that she was closer to the air inlet at the bottom of the tent and that could be getting a blast of cold air when the extractor comes on in the morning. I've a had a bit of a shuffle around and brought her into the middle of the tent. Other than that she's growing well, if anything faster than the Chocoloate Orange which is in the same tent. She's got a really nice grapefruit smell at the moment which is really appealing. The photo was taken earlier this week, the leaves still have curl gut growth has continued, if I'm happy that there isn't a major issue I'll start LST next week.
