Just used their base nutrients with some AN big bud and overdrive and I'm seriously disappointed. I've been growing for over ten years and this is the worst product I've ever used. I have experience with canna, advanced nutrients, botanicare, gh, and sunleaves RW. If this Dyna was good to you you're probably missing out on bigger and better things. Waaaaay less crystal production and general weight along with a shitty look. Small stems with barely any color coming out. I live in Colorado so I'm pretty picky. Quite a few people on this site are really cheap and love this garbage but its trash for Colorado standards. I wish advanced sensi A&b never went to that ph perfect nonsense. Bottom line you get what you pay for. Don't be fooled by this inferior product and a few budget grow peeps telling you it's good.
