400wat hps and MH for flowering?

Im currently flowering with a 400 watthps and a 400watt mh...Am i wasting energy by using the mh?...or will the mh make a diference, giving me a bigger yield?...I ask because I know that mh's arent too efficient for flowering....just need some advice!!!!

I've read that using mh in flowering will make your buds more potent and develop more trichs to protect from uv light
If you were to use just an mh light your yield wont be as big but your bud will be more potent, whereas if you flower with hps you will get bigger and fuller buds, i say use both mh and hps and if you dont see much difference, on your next grow just use hps
im no expert im just giving my answer from what i've learnt around here, someone correct me if im wrong

Thanks for the advice man!!!...Any more input anyone?...

You'll yield more because of more light and since it's dual spectrum the plants won't stretch as much due to the MH bulb. I've used it before but now I use a 1000 watt and a 400 watt HPS
