2nd Week of flowering, she is bushing up well. I keep hearing about the first 3 weeks of flower stretch, doing my best to try and manage that stretch to widen out the girl so the bud have better airflow around the buds as they develop. Don't really know what to expect for stretch as this is my first grow but for lots of people it seems significant. I'll have to implement a scrog if it stretches a lot, but up until now this girl has been very short and bushy.
