New grower. I planted 1 northern lights AF which sprouted first week of April. Now at week 12. Three weeks ago (wk 9) I started to see some white hairs in a few places. During these 3 wks I am seeing white hairs in more locations along the stems, but only a couple hairs in each location. it seems that I should be seeing a lot more of them by now. In fact I thought I'd be harvesting in another week or so. Would it do any good to switch to 12/12 even though its supposed to be an auto-flower? Also its over 4 ft tall and outgrowing my small box. Thanks for any help or suggestions.
