I've been working on these little ones since February.. used back-yard soil and didn't feed them npk since birth, except for water and sunlight.. they've come a long way.. tho they're from the same bag, each grew differently.. about 6 weeks into flowering. Calyxes are swelling on both.. but one has more crystals than the other, also odorless. Unless I touch them.. kinda have like a lemony smell..
