Grow Mediums Reverse Osmosis and cal mag HELP

[kosherkush]

HEY AFN,
MY tap water ec is bouncing from 0.6-1.2 so i had to make a switch to RO, now my question is
im using an ATAMI nutrients set, after filtering my RO ppm comes at 20(means EC 0), how much CAL MAG should i add before other nutrients? in the past two weeks i been upping to 240-300ppm with Advanced nutrients CALMAG PLUS and then coco a/b etc.

Is that a good range? or im overdoing it? im seeing some strange disformed curled leafs.

sorry dude I don't use ro water but I always start my calmag at half manufactures dose and keep an eye out for any problems upping it if needed my tap water is 0.50 ppm and 7.2 ph post some pics of your plants in natural light give people a better idea

I go up to 240-300ppm seems to work great,
