Got 2 lights . Light settings advice

Hey all, so i recently aquired a second CLW SS550. I have one in my 1.2x1.2 can i put the second in there too untill i get my sevond tent and if so should i dim them both down abit so not to cause light stress??

Current settings on 1 light is 99red, 99white, 39blue. Entering 3rd week of flower.

You can. Just to even out light spread. And remember in flowering, you do want more red. Now ive heard the last couple weeks, blue brings out terpins and smell. Someone more informed will be along later
