one more question though, the top leaves (biggest plant 20 inches from 400W HPS light and smaller one 30 inches away) of both plants seem to have a very very slight tint of a darker green... is that too much light? should i put glass between the light and plant to let the light through but block some of the heat? thanks
That's too close! 400 watt lights should be hung around four feet. Check out this link: http://greenmanspage.com/guides/lightguide.html
About the glass: It isn't beneficial at all. It will only act as a magnifying glass, and gather alot of unwanted heat around your plants.
