You would normally see intersex traits by week 3. Late intersex issues express as naners.
I haven't crawled into the tent since around week 4-5 but the side windows give pretty good exposure. At this point, if there's nanners, they're just gonna happen, as I can't see them within the clusters.
My main concern now, in terms of surveillance, is looking out for any signs of PM or budrot. It's been pleasantly cool and moderately humid (in the tent) for all of May and a good part of April. Nice for weather tourists, worrisome for growers
