Week 8 and the flowers are starting to put off a weak bud smell and the trichomes are showing up like wildfire. I'm still waiting for more hairs to start turning orange before flush.
Update:
5/13 and there's orange hairs popping up what feels like every time I look at the plant. According to the General Hydroponics feed chart, I still have about 2 more weeks before flush but I plan to continue to inspect terpene development incase I need to flush sooner.
