Blue and Red spec ratio

does the number of blue lumons in veg have to be the same as the red lumons in flower?? and when in flower is it good to have 1/4 blue L as red?

There isn't a mixed spectrum rule per se but, at a minimum, I would venture a guess that a 2:1 ratio would be effective. Others would say 3:1. Just keep the spectrum geared towards blue in veg and red in flower and all will be well.

so like 6000L blue in veg and 4000L red + 2000L blue in flower?

the plant getting a constant 6000L throught the grow is good?

It would be best to mimic the growing season so start with 2000 lumens and work up from there. Seedlings only need 500-1000 lumens to get growing.

The 2:1 ratio of red to blue will work well for you. The added blue will help keep the "stretch" phase to a minimum.
