CALi/MAGic by general hydrophonics

Has anyone used this product, How often should I use, is once a week with feeding too much?

once a week should be fine never used it myself though

50- 100 ppm with ro every watering works good. Has much lower Nitrogen than other cal mags so some peeps like it in bloom.

I use it at a rate of 2mls per litre every second day. I run rockwool though.

is the cal/mag more important in veg or flower or both? Is it true it will help buffer the ph in soilless mix, such as promix?

I dont use the GH CaliMagic I use GO Cal Mag +. With Ro water I feed 5-7mls per gallon every watering.

Depends, if you live in a soft water area or use LED you will need to use calmag every watering.

I just started using this product with my coco and today was the 2nd time using it in a row. I will give the heads up in a day or two of how the girls reacted.
