About 2ft from canopy. just put them in flower so they're gonna stretch a bit. I haven't dimmed the light so I think full power. Do the plants need a lower EC than hps? and Does the light have good penetration?

EC depends more on other things like humidity and CO2 levels. Some people say they need more cal-mag though with LEDs. I haven't noticed any difference so I don't use it.

It will have better penetration because of multiple sources of light, but it doesn't really matter if it had less because it's still putting out twice as many grams per watt.
