It all depends on how much calcium and magnesium is in your well water. You only need CaMg if you have very soft water... or if you are growing in coco. Adding molasses or other carbs/sugars isn't extremely important. It will grow "plumper" buds. Its really only important when blooming.

what kind of soil you re using for your purple kush ? I love to grow OG purple kush myself...right now i got some beans to grow again in a few months....did you pre mix soil with any dolomite or garden lime ? then it dont need cal/mag, if you re using RO water then use cal/mag. hope this will help you.

Actually the cal/mag in hard water is not readily usable by plants, even if you have hard water with cal/mag in it you still may need to supplement these nutrients with cal/mag in a form that can actually be absorbed and used by plants. Carbs and sugars actually feed the benefical bacteria that aid in assimilating the non usable minerals in water/soil into forms that plants can use.

I run hydro and I add about 1 table spoon per 5 gal bucket every other time I water. You don't need much cal/mag as these are considered micro nutrients, but for some reason most base NPK nutrient feeds seem to be lacking enough cal/mag for cannabis so you have to add it. Best advice is to follow the manufactures instructions for your grow medium.
