Hi all
It seems to always be recommended to add Cal/Mag prior to other nutrients, but I have an almost full fresh 950l reservoir of nutrient solution and I've diagnosed a Mg deficiency.
I have Botanicare's Cal/Mag plus and want to add some in there.
My current EC is 1.8 using a local store's brand of nutrients (which I've done very well with for many years, just not at this place that seems to have softer water).
Do I need to dump my reservoir and start fresh or can I add the stuff into my current reservoir?
How much of an EC increase in Cal/Mg plus should I be shooting for in order to combat a Mg def? 0.2? 0.3? I'm at the end of the third week of flower on a recirculating rockwool F&D system if that helps.
Any advice much appreciated
