Just bought AN Sensi Cal-Mag Extra. Do I half the concentration listed or go full strength. As a preventative, should I add to every feeding? When is best time to begin extra cal-mag as a preventative? Thanks.
What are the numbers of your cal/mag?
They don't list the percentage of cal/mag but I would go half dose at every watering until week five then go full dose.
The link he posted didn't show ingredients but yours did Sour,thanks.I guess the pic doesn't show?
Cal 3.2%
Mag 1.1%
Cal Mag Xtra is 4-0-0

There is a load of N in there..
What kind of light, soil, nutrients are you using?
As previously mentionned if using LED a lot of growers will be using it more often and to a higher strength than other lights user.
