First the grow looks great. The plants look healthy and I say just don't bf it to death and mess it up.
Second. I have education in electrical. It may just be me, but, when I see all them lights and adapters being used it just screams fire to me. Just a personal thing. I personally did CFLs my first grow and built a fixture to hold 4 of those ginormous 65(actual) watt CFL's, soldering and everything. It worked fantastic. But, been using LED since. May try a HPS someday, but since I only do one plant, seems overkill. My LED probably pulls 100-140 watts tops.
Just me, I would def go a different direction with those lights. Probably 99% safe and ok. That 1% is a mother fucker tho. Other wise your plants look great.
Peace and best of luck.
