If you can, moving the heater just outside the tent should work well enough. Cannabis likes cooler nightime temps and during later flowering in nature is accustomed to fall's cooler nights outdoors. Just so it doesn't get much below 50 deg and you should be fine. 60-65 is optimum at night. Obviously being so directly affected by the heater, the nearest two plants are suffering. Dry hot air right on or near the plants even during the daytime is not recomended anyway. Some have said, and I've wondered why myself it can get into the 90's outdoors in the heat of the summer and MJ does just fine. But the same doesn't apply indoors, even with good air circulation and higher humidity. 90 deg will have the leaves noticably wilting and growth slows. Looking much like the two plants in the pictures you posted.

Oh, almost forgot to answer the most important part of your question. No, the plants won't die. Just cool things down at night and they'll recover well enough. Though in the end they probably won't yield as much as the plants that were not as affected.

Thankyou man, much appreciated, was a horrible feeling when i first saw them im gunna give them plenty of water and hopefully they will pull through

They wil be fine, you are in the home stretch. It is pretty hard to kill them at this point.

Why do you have two threads about the same exact thing? Gawd damn stoners.
