light question- square ft

Hey everybody hope all is great! Have a quick question about lumes and square ft. In my set up I'm around 4200 lumes per square ft. Have a mix of lights but mostly in the red spectrum do to the fact I'm in flowering stage. I do have 13,000 lumes in the blue range just to mix it up alittle bit. My question is this a good amount of light ? I hear min. You should be at is 2000 lumes per square ft I'm double that but is it enough have about 100 watts per plant also. Just looking for a idea where everyone else is at and if I'm on par. I will be adding more cause next run I'm doubling my plants but would like to stay in this range. Thanks in advance for any input you guys might have I know its a small grow but its coming along nice.

I have heard to not go over 67.5 watts per sq/ft.

Not over that I'm at 33 watts a square ft. Never heard going by watts and square ft but thanks for your input. More of a lumes question then watts I always thought the more light the better. Any other advice or input would be great thanks ....

60 watts per sq ft would be ideal....... Look at it this way.......1000w=4x4 600w=3.5x3.5 400w=3x3 does that help??
