Plant dying of old age...

Evening all,
Heres my Jack Herer auto, supposedly 9 weeks...at 20. She seems to be going downhill. Im struggling with high temps and humidity (30°/60%) and she really doesnt seem happy. The lower buds are looking like absolute crap and that seems to be slowly working its way up. Also the tops of the buds are starting to go brown. Some buds are starting to topple over, the stems seem to be losing their stiffness. Foxtailing. Very little stickiness to the buds very little smell.
If all was well id let her go a bit longer but i think im close enough to chop her now rather than leave her to deteriorate any further.
60x60 tent, 135w QB, DWC, ph in range, about 1000ppm in the bucket.
Yeah I know she looks like crap, go easy guys only my 3rd grow!
Whaddya reckon?
Cheers!

Ya it's not gona get any better....
Did you run into heat issues? Lights close to the plants?

I'd chop. Ever think about using feminized seed instead of autos?

Having your lights to close causes airy buds and foxtailing... Time to harvest!

Many thanks guys. No i think my light was at a safe distance about 20'.
Will chop her down tonight.
Cheers!
