Have Area 51 RW 75 and used only white on free autos and pretty sure flowering has started due to yellow/white hairs on top(thread on auto section). Do i now use only red or keep them both on for max light? Thanks.
Red only, or Red and White for Flowering?

Use both white and red when flowering

as theirs no such thing as seen by the plant as 'white' light
stick to red(2700 kelvin) only as its this red that stimulates the hormones for seed set
allowing the budding process to proceed in the dark 12x12 off time
white light is actually cool white or light in the 6500 kelvin range
used to stimulate horizontal growth. leaf matter during veg
red /2700 kelvin colored light goes opposite in veg ..makes the plant go vertical
its important to keep this in mind once in flower/bud, red is all you need
ask any hps user
good luck

Also as its auto, 12/12 reduces growth. Still deciding between 18/6 and 20/4. Ill use them both as thats what i thought would be best.

If memory serves me right that lights has 5600k whites and 630 nm reds.

There is no evidance to support that cooler or blue light increases foliage or node spacing. Prof Bugbe at Utah state who is one of the leading experts on plant lighting has much evidance to support this. Photons are more important for photosynthesis than spectrum.

Maybe not from the "official science community", but I'd definitely take notice of SuperAngryGuy's testing - he's done quite a bit of it:

Again, all about photons. Ill find thr paper. Have seen that before. Have also done tests myself. I prefer the higher photon of HPs over MH for entire grows before I used led.
