Ya bro your Veggies are looking good. Temps above 85 degrees slow growth rate and actually close stomata. You'll definitely see a huge increase in yield if you'll be supplementing co2 next round. The best way to deal with heat is inner-cooled hoods pulling in outside air straight over the bulbs without ever touching the plants. Have your co2 kick on at 1000 + ppms when your lights kick on for their 12/12. At night when your lights and co2 shut off, kick on your carbon filter to refresh the air. If you invest in co2 you'll need cooled hoods and a sealed room. You definitely need a dehumidifier if you dont already have one too. Other then that bro your set up is nice! Good luck
