they LOOK like they like it so far 
I have two BLURPLES (the cardinal sin in growing evidently lol) which equates to 390W overtop of 2 plants and they are flowering up NICE and thick You should be fine for veg for sure but may struggle with that combined wattage getting 3 to flower. I know they WILL do it, just might be a little more “airy” (fluffy).
They’re two weeks and three days into flowering
