Hi Mainegrown,

With my central heating on in my home the temps in my cabinet are pretty much the same as yours 78-80 F.... ...25 c when its off

So I dont think It's that that's making your girls droop....

Form the pictues you've posted up already...
(Looking nice bye the way! which strain are they?)

They look pretty much like my girls do once I have over watered them slightly!

When the air's too hot and you've got a fan blowing hard... you get a kind of wind burn.... yellow speckles that dry out and go brown.... exactly the same as when your plant leaves accidently touch a CFL!

do you know what I mean? Is it like that?

It's shit when after all your hard work you seem to just be treading water!

I'd go for the troubleshooting form! :thumbsup: I'm sure we'll all help you get the problem sorted! :thumbsup:
