im just trying the canna 2 part plus , i cant speak for it yet. it has cal mag in the coco product lineup. i just wanted to say that i used the pure blend pro only, throughout my crummy heat riddled run, anyway, i dont recommend pure blend pro only as its not as flavourful as when i used pure blend pro bloom only through an entire run, that was tasty.(ier)
Why 2 part? Imo get away from liquid ferts and move to dry ferts. A lot more cost effective. Liquids need 2 or 3 parts simply because they cannot be mixed as concentrates. I like mega crop but there are plenty of good out out there. Liquid nutes just put everything in 50 different bottles and charge you an arm and a leg for the water and the miracle claims they write on the bottle.
