cal/mag question?

i recently switched to a water filter system and noticed sine i am not using tap water that i am getting a cal/mag def because of the filter. i am bout to strat using molasses and was wondering if the cal/mag in the molasses will be used by my plants since it has alot in it? or do i have to use a cal/mag additive?
anyone know if the molasses should do the trick and my plant would beable to use the cal/mag in it?

You need calmag.

You should not use molasses unless you are flowering your plants (and even then, I still do not reccomend it personally). There are much better carbohydrates and sugars available to flavor and fatten your buds.

There is the short answer. :jointsmile:
