Switching hps to mh

Ok need some help. My 400 watt hps keeps shutting off at random. Not sure if there's a problem with the light itself. Will it hurt if I switch them to my bigger tent which I'm running a 600 watt mh. They are currently under 400 hps. Week 3 veg going on. I'm waiting for a call back from the manufacturer. But don't want to take a chance on hurting the girls. Running 6 g13 pineapple and 4 g13 blue og. All are around 1 ft in hight and are 3 days into week 3 veg

Switch theyll be fine, even do better under the 600mh.

Yea switch them. Vegging is best done under mh anyway.

thanks guys just finished the switch
