I second 912..... and for the hard core LED guys running daily feed schedules and blind the plants up like crazy the amount of cal mag I have to use is 2 to 2.5 ml per liter when in stretch and early bloom. So if my cal mag had to run that high to keep from spotting up and early yellowing I would probably get leaf curl from the added N and also burnt tips.
But lowering the dose only gets me a cal or mag def plant....
Now using the GMB ypu can drop the grow a little as well as the micro to offset that. But lowering base nutes to Cover something you can avoid seemed counter active to me.
I use general organics cal/mag sup 0-0-0
