No. Those are beautiful looking plants and you don't have so many leaves that they're causing any issues.
One of the primary functions of the vegetative state is to maximize the size of the canopy so that it can capture more light. The more light a plant can capture, the more it can use (photosynthesis) to generate glucose which it uses for growth.
You're giving your plant a good amount of light (huzzah! since most growers don't) and they're responding (the leaves are horizontal, rather than drooping slightly). The color is uniform (though might be a tad dark) and no sign of nutrient imbalance. I would just leave them alone and get them to at least 600µmol (they're 4-5 weeks?)
I use a veg light (LED) to produce plants that are short, compact, and have a lot of leaves. By day 21, when I top my plants, the foliage is so thick that it's hard to get into the canopy to find the fourth node. It's a little frustrating and, I do have to defoliate when I flip, but as the plant grows vertically in late veg and in flower, the plant "outgrows" all of that foliage//the foliage thins out.
