I would have thought the tops would start frying before the lower leaf tips...

Rule of thumb: Hold your hand at plant height - If it's too hot to keep your hand there, its too close!

Yellowing tips is a textbook sign of over-fertilisation, but I am not 31337 enough to say if thats the case here...

^^^---totally agree. 'If' that's nute burn I 'd think it's getting pretty extreme and hopefully somebody comes along that has an answer/cure for you.
What are the white specks on the leafs.......?
Good Luck with your girl!

.......that pic of the spots looks to be the trich's(good). The one in your earlier pic looked to be mite damage......you might want to take a look with a magnifier.
Have you cut those bad tips off??<---I 'd do that asap(just the bad parts) and hopefully someone will chime in with some more ideas for you...
Just out of curiousity, is your humidity real low??<---like minus 20%?
