Is my Venus healthy?

Hi! This is my first time growing Venus flytraps. I’ve read as much as I could to learn how to properly care for them. I’m using distilled water, and the pot sits in a tray with some water. The only potential issue is that my apartment doesn’t get direct sunlight, so I’m using grow lights (6000K, 20 cm above the plant, 12 hours a day).

I wanted to check if my plant is healthy because some leaves have turned or are turning black. I think everything is okay since the traps are fully functional and the plant is producing new leaves but I want to be sure.

Just in case, I live in the Southern Hemisphere, so it’s summer here (in case anyone suggests dormancy).

Thanks! :)
