I’ve read a bit on here about flushing the soil for a cal-mag deficiency. Would I flush with pure RO water then do a watering with cal-mag in it or do you flush with RO and mag-cal? If it’s not a real bad deficiency can I just add in some cal-mag to my nutrient mix? I found a bottle of Fox Farms Cal-Mag at my local nursery mis-priced for $9.00! So that’s what I’ll be using. Thanks
