Should i add?

Hello !
I currently have three plants that are roughly 45'' tall (i have about 8 feet of height space) in a space that is 28'' across and goes 32'' back. I am running 650w of daylight CFL's and LED's that is producing 10,000 lumens. They are about 2 - 3 weeks into flowering and looking gorgeous, though i'm seeking expert knowledge in regards to the lighting. Will this be enough to carry me the last leg of the grow? Thanks!

yeah 650watts is good for 3 plants i dont know if cfls are a good enough spectrum to produce nice flowers thou but i dont mess around with cfl's in flower. hps or led is the way to go.

880 watts a meter i like

The lights are 450w CFL and 200w LED, to be exact. If i add 200 more watts of LED would the changes be drastic? If i replace the CFL lights with LED can i move my plants closer? Do i need to add a different spectrum of lighting or will my daylight bulbs be sufficient? Every response is appreciated and welcome!

I use 2 full spectrum 300 w leds through veg and flower.
Unique terpene and oil production lower quantity but quality.
The height from the plant ... Use your hand as a meter.
My lights sit 12 inches from the top of my girls with no issues.
