I'm not sure if this strain typically has purple or red stems. She's a Cannatonic from the Cali Club.
If she's bred for Cali weather, could the purple stems be related to nighttime cold stress (I'm in BC, Canada) ?
The stem bulge was a break. I wrapped it with green tape and proped it up at the break with small plastic vial. It healed well and the stem is overall quite healthy (I think).
The lighting in the picture is bad (newb mistake, I apologize). I'm running 1 T5HO 18 inch and one T5HO bulb in a 78 L Rubbermaid. Inside is painted flat white and lined with reflective panels. 2 passive intake and 1 exhaust (6 inch). Also 1 overhead reflector.
She came to me in a 20 L (est) grow bag which was too large for my space. I also worried it would make watering a challenge. Why ? Because I'm new, over attentive, and prone to over watering. So I transplanted her into a smaller container.
Stem break ? Transplant or cold stress ? Funky genetics ?
I'll try taking some more pics. Thanks for the input.
