Lambs Breath Autoflower

This plant is now in the 13th week from seed emergence. I had considered doing a partial harvest since the 4 main colas are closer to the light than the remaining smaller buds within the plant, but it seems they are maturing along at about the same rate. I inspected the trichomes with a jewlers loupe and all of them still appear to be clear. The flowers have really added some girth over the last 14 days, so I'm hoping for more of the same over the next week or two as the plant matures completely. Still just watering with tap water at a natural pH of 6.9 and not adding any more nutrients to the soil.
