i put in a RO system and im using calmag i followed the instru. my ppm are at 440 i think thats a lil high (before calmag 0 after calmag 440) is this ok ?

Eeehh,WHAT?? cant make any sense of that.

440 ppm with the Calmag is probaly fine. a lot of calmag solutions have other nutrients in, i know mine is 2-0-0 with micro nutrient, zinc, iron, and a few others i think. If your water is not really nasty, you can be fine with not using an RO and not buy a calmag, but sounds too late

I'd say a lot of that 440 is natural minerals. You're good as long as you're plant is acclimated to it slowly. I wouldn't do full strength if this is the first time introducing your babies to it. How old are the plants?
