So this is a mystery weed I got for my bday. It's growing like crazy and it's only on it'd first 1 week and 3 days of nutes.

I've been having a little bit of trouble keeping my tent under 85 sometimes even up to 90 degrees I have the air conditioner going and two fans. But when the air goes off I can't really do much without pissing off the people I live with. Any suggestions?

Plus, not on my MJ but on other plants I'm getting this weird powdery stuff and some weird slime on the rapid rooters.

Do you have a blower for exhaust on your tent?
When I first used a tent I thought I'd be fine with regular duct fans, but was not. Really need an actual blower to exhaust that warm air.

You want your temps in the mid to high 70's for the most part, can gradually go as high as 80-82 when they're older. Watch for signs of heat stress, they're probably already stressed if temps are as high as you said.

Happy growing man! Smoke up!

I have ducting close to the hps light and reflexer that runs out of the tent to a in line fan outside the tent.

There is a little heat stress on the second set of leafs under the fan leafs.

Could it be possible to run some ducting for ac vent to a inline fan to the tent to cool it off even further?

Like from your room's central air system to your grow tent? I've never heard of anyone doing that before, but that doesn't mean it hasn't/can't been done..
There's always a way to get better ventilation for your tent, it just depends on the layout of your setup and how much you wanna spend.
Personally, I wouldn't mess with your home's central air system. In my 3ft tent, I just have a 90cfm duct fan for intake, and a 200cfm blower with a fan speed controller for exhaust hooked up to a carbon air scrubber; and all the vents at the bottom of the tent open. The blower is strong enough for the enclosure to get decent passive air intake from the 3 bottom vents. With the AC on low in my apartment, it stays between 74-79 inside tent.

Well I was just thinking to zip tie the ducting to a vent in my room and have it connected to another inline fan that would take the cool air from the vent into the tent then have a carbon scrubber at the top

I also had some browning of the roots so I fill my tote up about a inch under the net pot to see if it helps but there's a ton of roots! It's awesome to see
