Check out your instructions for the mars hydro and it will say use Xtra calmag. Something with quantum board LEDs and calmag deficiency. Mars started putting it in the instructions 👍🤜🤛 advanced nutrients sensi calmag Xtra is awesome bro. It has some iron and nitrogen in it to green them up 👍 iron helps it absorb the calmag so it's the best 1 to get
