yup, those are just swollen calyxes, no worries ... also normal for growth to slow to a crawl late in life like this ... you may just be getting near maturity, photo 'looks' like all the trichomes are milky ... 38 days, though, should be looking at another couple weeks, minimum ... keep your eyes open for amber trichs, then harvest ... plant looks OK, otherwise, for a bloomer :smokin:
