Make sure your exhaust fan is strong enough to blow thru the filter, a lot of times it is'nt. Run it without the filter for a couple of hours and see if the temp comes down.

Yes, it's hurting them. Do you have any fans on intake? Are you pulling air out from the top of your tent? What is the cfm rating on your outtake fan? What is the cfm rating on your carbon scrubber?

I am only three weeks into it. Yes I have intake pulling cold air from outside. I have a four inch exhaust. Carbon filter is not hooked up yet. I am not sure of the cfm rating. My one plant the bottom set of leaves (out of six sets) the two leaves turned kinda yelllow and crispy. The other for are fine. My humidiy runs in the thirtys. I live in the northeast so the intake air is cold. The 400wt hps is about 18 inches away. Thank you for your help.

If you don't know the cfm rating, just tell me if it feels like it pushes a lot of air or not. If you put your hand in front of it, does it just feel like a gentle breeze or a hair dryer? Regardless, it shouldn't be getting that hot in a tent your size with a 400w hps. My tent is smaller, and i have the same light, and never go over 86 -- usually between 78 and 82 with lights on. Where do you measure temps, at the top or the bottom of the tent? If you measure directly below the light, you may get some radiant temp readings, as well. I have a cheap thermometer from a basic hardware store for inside/outside temps that allows me to measure at the top of the tent (heat rises, right) and also at or below canopy level.
I think the deal is you're gonna need a more powerful fan. Where's you get the one you have? how much did it cost? what kind is it? if it's a duct fan or whatever, those won't do the trick. They can help with intake, but for outtake you need a real fan, which is gonna cost around $100.
