Lighting advice

[AirForceReefer]

Hello everyone! I’m still relatively new to reefing but I run a 75G mixed reef tank with a 32” SB Reef Lights Elite for my lighting. I noticed some bleaching on my green slime frag so I did my par testing and these are the results for the highest part of the day. My question is could I potentially be running my lighting schedule for too long in total and that is what’s causing it? I’m getting phenomenal growth everywhere else. Second pic is what I bumped it all down to.

Nothing is even close to being 100 PAR, it shouldn't be bleaching due to too much light. Is it the skeleton turning white? If so, it is dying from too little light. The 32" reefbreeder honestly isn't enough light for a tank being 48" long. Unless everything is placed directly under the light and it's cranked way up. As it is now, the front/back glass and ends are getting very little useable light.
