90 degree temps? Well that sounds like the problem buddy! I would seriously try to get an air conditioner, or stop running so many watts until you can properly cool the area. Those high temps or gonna make your buds thin and lanky with no weight....you should look into adding C02 but even then you need 85 degree temps.
Also you can run your lights at night to enjoy that lower temp and rates, then cool your room during the day with less energy consumption during the dark period.
