Leaves are sites of photosynthesis
Plants are the most common autotrophs in terrestrial—land—ecosystems. All green plant tissues can photosynthesize, but in most plants, but the majority of photosynthesis usually takes place in the leaves. The cells in a middle layer of leaf tissue called the mesophyll are the primary site of photosynthesis.

 
What if leaves are covering new branches? I have been low stressing my photoperiod plants and fan leaves are covering tops. The plants are 23-25 days. I plan on switching the light cycle at 5 weeks or 34-36 days old. Some of the fan leaves are already massive. If the fan leaves are removed, won’t the new tops photosynthesize more? Removing the fan leaves may increase the potential of the tops because they will have more opportunity to photosynthesize.

Tuck them under the sites its covering. But getting rid of leaves especially at the size its at is ill advised.

Should I start defoliation on this one? Or is it best to not defoliate during this time?
Nope, not even close. You will just slow down growth. I suggest trying out pinching your dominant tops to create the structure you want before flip. By pinching the dominant tops you temporarily create auxillary dominance and as a result the lower branches grow.

You basically lower auxin transport for a day or more to the main tops by pinching and/or breaking the stem.

I'd defoliate that plant a little bit not much since its already topped. I do defoliate & strip a few nodes after the top node. I do that to train my clones to grow side branches without topping. When you defoliate it makes the side branches have to grow their fan leaves out bc main cola doesn't have big fans now. You can kill plant if you strip away to much tho so I wouldn't advise newbies to do this technique
