Sensi cal mag xtra - Advanced Nut. - PPM ?

Love the experience and all the work put into these answers gottagrowsometime, Legend

Normally I'd say no. Very hard to get burn off calmag, but sensi cal mag extra has 4% N in it. And has other trace nutrients. So what you are looking for. 250-300ppm + your waters ppm. So if your water is 120 and you want a mix of 250 of calmag then your mix will be 370ppm. Be careful when giving this one especially close to your grow. Most calmags don't have N in them. But you didn't get a reg calmag. So just be careful when applying. + you won't need it until you need it. In most cases that won't be until a few weeks or until you get close to flowering or growing in coco. As for your base nutrients. 4-600ppm after 1-2 weeks. Then you can bump it up after a while. I have full 14 adv nutrient line. I don't use it anymore but it burns easy and is full of salts so be sure to come behind with water feeds or at least once/twice a week. Good luck.

lower your grow nutrient ppm by the amount you add your cal/mg ppm at.
