CalMag - Frequency of use in soil ?

[HotLooSey]

Growing in BioBizz All Mix...

I do the every third day fertilizing in veg and Flower until I feel more comfortable with greater frequency.
I use CalMag in every Fertilizing Feeding. Should I also use it when I water? Seems like a product everyone promotes in the shops and uses.
Thanks...

Just with the feeding is fine.

I use every feeding as directed up til about 3 weeks before harvest.

U guys recommend just using when feeding even w/an RO system.

I would use it carefully if it were me. Dosage would be dependant on the ppm of your water. I would go with around 2.5 ml per gal (1/2 strength) and see how that does. Watch for signs of Phosph. def as this may be a sign of too much mag.

Sounds about right, makes sense. thanks.
