That is great information and I appreciate that. So as it is in veg, your lights are pretty close to the canopy, correct? Then when she goes to flower, raise the light up not to hi but adjust as she grows taller for a bigger yield?Generally speaking 30-35 watts per square foot is a good rule of thumb.
I'm using a @VIVOSUN 650w in my 5x5.
It's a brilliant light, I've had fantastic results with it.
It's only 26-W./sq/ft.
You can do a lot with less than 30.
But that is a good starting point.
Always buy the best you can get , I recommend.
I see people with something smaller than they want all the time.
Buy the right one the first time.
Light requirements in flower increase.
But plants grow up into the light usually reducing the height from canopy level.
Usually this is enough.
Unless you have a 10 foot grow room most lights are stuck at the top with the plants close , by harvest.
So usually not much room for adjustment.
There is something called DLI,, daylight integral that will tell you how much light she is getting.
You read light par and multiple it by duration of light.
That will give you a better idea of light intensity.
That's a lot of math I don't do.
I read my canopy and can tell if I can increase my strength.
But as a rule of thumb I have my lights at 100% before I go to flower.
Then I keep my lights close as I can without adverse effects.
Stay safe

I am definitely going to look into the light that you suggested and do some more research. Thank you for your knowledge
