Having trouble identifying the issue

Blue Dream photo about 5 weeks from germ
Being fed only mega crop and cal mag until flower pH to around 6 Temps stable at 78 and humidity right around 50
Under HLG 550 eco and a blurple in a 4x4 with some other photos and WW autos. Not noticing this anywhere else

Too much light, if you can dim the fixture. Also looks like a bit of over feeding? Can you fill out a support ticket?
