Beautiful setup,
Are u running co2? If so those daytime temps are fine. Though I would still drop nighttime temp to low 70 s just to give those leaves a nice rest. If ur not running co2 I would drop the overall temps down to 78 or 80 with night again near 70. IMO the plants look slightly heat stressed but still very healthy. Other than that, mayBe bring up the ppms as to combat any microdeficiencies. Great job tho! The room looks legit.
Remember its always better to pay more to keep the environment in check than get screwed with a shwaggy crop.
Good luck
Chief
