Lighting placement question

I have a magnum 357 LED and 2 90 watt sunshine UFOs. I have started 12 plants after sexing I will be a 5 or 6. should I use the magnum as the main light and the 2 UFOs as side lights or just use all 3 as main light.

I like to use my smaller units at an angle blasting sideways, you might have to keep your lights slightly farther to avoid weird burn with the lights overlapping especially when the plants are small, but it really helps when the buds are getting fat. This way, whenever you run out of room you can always use those secondary lights as main lights to finish up a plant in the corner.
