are you just letting them grow up through the trellis, or are you bending them down and letting them grow up through?
Mars Hydro grow lights are best in the market. i am using mars hydro LED grow lights form 4 years. to be honest they deliver what they promise.
it can easily cover the 4x4 grow tent space. Reflective mylar is also responsible for the light absorption rate.
GROW MEDIUM: Do not use soil, use coco coir, better then rockwool
Update:
Today I did about 3 1/2 hours of tucking. And I didnt finish. My back started screaming mercy before I got done. But I got 3 of them done. All thats left is LS2. I will do it tomorrow. It got me out of going to the gym tho so I cant complain too much (actually I got Stretch done too but didnt take a picture at that point. Was ready to wrap it up and take a break.

I feel your pain on the tucking and training. Pain in the ass but sure pays off in the end.
Although the pic is blurry, I don't think you are dealing with light burn. For the leaves to be that burnt, the pistils on those buds would be brown as well. I think you are dealing with a nutrient issue, but I'm still learning myself so just my rookie opinion.
get a dehumidifier and get the RH 50-60%.. youll see micro nutrient deficiencies from low transpiration from such high RH in flower..
nice buds, bro
