I reckon we are about neck and neck with this grow, some of your pics look like you have been in my grow room taking photos.
Interesting what kaosangel says above.
The biggest problem I have had with this entire grow is keeping the temperature down, my lowest yet temperature was today and was 27.5 C which I think is about 82 F.
My average temperatures these past few weeks have been around 32 C , around 90 F and I believe autos do better at a max of 80 F so I am amazed I even have a crop growing.
Maximum temperature in my grow room so far is 34.9 C yet I still have red/purple tones so although I dislike disagreeing with other forum members, I have to say colour variations can not be temperature related, or more to the point, certainly not in my instance.
