Not having the red leds is not hurting you at all. Corals have very little need for the red spectrum of light, crisp whitee and blues in the 400-460 range will cover the spectrum nicely. Sps in particular grow very well more on the blue end of the spectrum. Water filters out reds so corals in the ocean have adpated to thrive on blues light that phototsynthetic plants on land.
