AN sensi 2 part and cal mag

Hey all

Im about to start my first rez soon and was wondering for the rest of my grow, if im using sensi grow a + b do i still need to use cal mag plus? sensi has cal and mag and iron right on the back of it, among its other supplements so im thinking no.

I own both and theyre unopened so this would help greatly.

It was my impression that you need cal mag if you use ro/di water or distilled water not so much tap water and certainly not well water

You will also need the calmag if you plan on using coco substrate in your pots.


AN told me in an email that if i wanted to try their products then i would need to add 200ppm of Sensi CAlmag as i grow in coco.
