Strawberry Nugget in a 2x2

all still chugging along. trichs became clearly visible on about day 44, which is similar timing to the mint jelly i just grew out. basically do leaf tucking every other day, but have not trimmed more than 4 or so leaves total over the life of the plant. by day 44, aroma is also getting pretty strong. fills up the room within 10 seconds of opening the door. strong sour smell with a hint of skunk at this point. update: feel confident i'm not imagining this, but top bud is turning deep purple as of day 48. could it be a purple pheno?
