i have heard this before but cant find a lot of info on it. what is it how does it happen and how do i get ride of it?
There are lots of ways, we need more situation specific details to make an analysis of what the cause may be. Pictures are even better than text.

[quote name='OSUB']either: A: your room is too hot B: your room is too dry C: a fan is blowing extremely harsh on your leaves thanks for the ideas i have been battling heat issues since i started. im growing in an 8' walk in closet so its hard to get the heat out he room. got a 4" intake fan that brings fresh air in to the the room but no out take from the room.(i don't know if cutting any more holes in the house is an option) humidity 49-68% turned my fan down and moved it hope that helps
93 and upper 80 degree temps will do it to some plants. An intake fan will not move much air if there isn't an outlet for it. The same goes for an exhaust without an intake.
