okay this is my problem ive been running my 12/12 cycle from 8pm to 8am to help with heat. temps stay between 75 78. but lights out temps can get into the 80s. what kind of problems can this cause? I am getting a lot of yellow and I heard this could be the cause. any suggestions?

High 80's you can run into problems, but at 85, while less than perfect, your plants won't suffer that much. I would like to see some pictures of the plant though, and see if the yellowing actually is a result of high temps, or something else. Peace

Its not the heat at night you have to worry about, its the humidity! Actually heat can cause issues too but if your temps go up so will your humidity. A/C units will solve both, Not only will it keep your temps but it will also draw moisture out of the air. Good Luck

same as in the tent 80 to 81. some days it has peaked as high a 85. but most days right around 80. what I wanna know is will it be okay?? because what I read says you want the temps to drop at lights out and right now its higher than when lights are on I mean there still flowering one is 4 weeks one is 2 weeks and the other is about a week in flower
