2' , 2 fluoro bulb fixtures for veg question

I have 2, 2foot fixtures that have 2 bulbs each , I watched a vid that said to put 1 coolwhite and 1 warm white bulb for each fixture for veg , I have 2 extra cool white bulbs.. should I put 3 coolwhite and 1 warm white, or keep it 2 cool 2 warm ?

anyone have any suggestions whether I should just keep it 2 cool 2 warm or what?

Having a mixed spectrum is good for simulating the actual colour temperature of natural sunlight. but in the vegetative stage the plants absorb the light from the bluer side of the spectrum.

My opinion for vegging, 4 cool white (or is it warm white?) 6500K tubes is fine.
