Sure, have at it!
More 660nm = fatter colas
Just don't keep them too close.
I see you have 180W.

If they are 1W. emitters, 5 inches is fine.
With most, knock-off UFOs 2" is good.
When using 3 - 5W. emitters, double the distance to the crown to avoid "bleaching" and growth suppression.

There actually is such a thing as too much light.
With white light, it's around 91k lux.
With dichroic led light it's a bit less because the plant absorbs more photons and reflects/passes less.

Shine on!
