Ok so I'm running out of vertical room. I'm keeping the light right on top of the plants but I still have to raise it every couple days. They're about 3' tall and I only have about 2' left before I can't raise the light anymore. I know I don't have to worry about them growing into the light but then the tallest one blocks out the light for the rest.
If I remember correctly, they've been in flower for 3 or 4 weeks, right? Most of the flower stretch should be already done so you should be OK. Not much can be done about the bigger one if you can't relocate it or move the light. Next run, if you use clones from the same mother, they should all be close to the same size. You may want to veg a little less, next time, if height ends up being an issue. The more you grow with your new system the more bugs you'll iron out.
Disclaimer: I still use HID and I'm NOT an LED expert. All of my LED knowledge is from other parties or research so I can't say from first hand experience one way or another. I also run a medical grow consulting business in SoCal.

The whole top of that plant is yellow. Not sure what to do...
Did you ever figure out what caused the yellowing that you experienced? I wondered if it was light getting to your roots before you covered the unused holes.
