That's only true for flowering, and it's not 100% essential. Just helps the buds thicken up since the the extra red in the spectrum promotes the creation of chloropyhll B better than blue.

I think Side lighting is very important when not using HID lighting. Even then it can help fill light gaps. It may help a LITTLE to have it pointing at the underside of the leaves, but moving it to the side would undoubtedly be more beneficial.
