Small plant problem : Asses please!

So i just put my plants into this room i made. I have been getting the environment just right. This morning i have noticed a small change in the plants. Two leaves are starting to curl under. One is getting heat spots, so i have moved my light. I am just wondering if the curling under is because of heat in the room, too much or not enough humidity, or lights too close.

Room temp : 85-90
Humidity 25-32% varies.

The first to pics are the two with curled leaves, the second is one in perfect health that is in the same room.

hello.....?

possible over watering let the soil dry out get a moisture meter, every 2-3 days or as needed

okay. So i have some intake fan and exhaust fan. I also have a humidifier because i live in a dry climate. I will turn off the humidifier and see if that helps. Also turn up my intake fan.

I just built this room last week, so they were in a slightly cooler situation.

thanks

your room is 2 HOT!!!! you want 72-75 and your humidity is 2 low i keep mine at around 50 when flowering, your going 2 stop all growth if you dont correct asap

I think i am going to buy a stronger exhaust fan today. I am leaving the door open, and have an oscillating fan, moving the air. My house is going to stink today....

I just use small fans and put them in places where i think hot air might be hanging out.
One on the ballast,one on the lamp,one blowing up under the plants. Those 5 dollar ones from walmart work pretty well.

Hmmm, This is all good advise thanks.

I am using the odor sok (Odor Sok - Activated Carbon Filters. Odour Sock makes carbon canister filters obselete. Perfect for hydroponics - Home) and have a inline duct fan that isn't cutting it. I thought the sok was rated for 340cfm and fan was 290 that it would be close enough. I didn't take into account that one: the fan has NO balls and its 290 is more like 190, because its not meant for what im using it for; and two: apperantly i can't read, because the soks 340 is actually 450cfm rated. SO i need to get more air moving. With my grow door open, the plants look happier, temp and humidity have dropped. Im not sure how to get the humidity up. My humidifier isn't quite cutting it. Finding one thats not made in china is REALLY hard! the only one i could find was a $19 special.

So yeah, more fans, im going out today for that, thanks

P.S. Wallmart is killing North America, don't shop there!! (not to sound ungrateful)

OH! And thanks for your help everyone!!

Heres the temp low down lol. You want to keep your plants at 78 degrees thats optimal temps. 80 is ok, but once you hit 85 all growth in cannabis stops until the temps come down.Get some venting in that place!!!!!

I have had plants outside keep growing just fine when it was much hotter than 85.......

you are dealing with different enviromental factors when outside. A plant that is grown outside is much heartier.

Seems to me that if you have proper ventilation there should be no difference.

put some buckets of water in your room it will bring your humidity up

Okay, got the fucking meat here.

460cfms. Much better.

I think the difference outside is you also have wind. The air in my little room is not moving, so the heat is concentrated at the plants.
