Yes sir. You gave the correct lighting for it, coupled with the excess nutrients in your system, algae will flourish. Water changes or an ATS or chaeto reactor.

Beware of recommendations by those who don't actually use their recommendation!!

The search function actually works quite well!!

It’s completely normal. I’d just get a good clean up crew and wait. Those numbers don’t look high to me but if you are worried about it, a macro algae fuge, algae scrubber or water changes will help export the extra NO3 and PO4. It’ll take time to balance your system with the new lights.
