Nice pics and nice plants bro... Yeah, u r only about halfway finished, and they still have alot of bulking up yet to do... I'd recommend feeding them with some black strap molassas/water to give the soil some natural sugars to eat, and it will help to break down some of the macro and micro nutes in the soil, making it easier to take up through the root system by making the minerals and trace elements more readily accessable to the plant, which will only help spur on some swelling, and it isn't bad for a lil' added sweetness, either... Just have patience... My flowering patch just got past this mid-stage of blooming, and r starting to really swell and chunk up every day a lil more... Itz very noticable when this next stage of growth begins...
