Messy situation just before harvest

Hi there!
I'm growing three White Widow Automatic.

First of all, due to a misunderstanding, they didn't get water for 5 days

The first and the second from the left are around: 10% clear trichomes, 85% cloudy trichomes (magnifier), 5% amber.
Here you go:


While the third one is: 20% clear trichomes, 80% cloudy trichomes, and 0% amber.
But, even worse, is getting some strange red/violet color as you can see in the following image:




What's the matter? And what should I do?

Other than obviously watering them, as for the first two I just wait until they're ready and harvest, right?
But for the third one?

Thank you for your time and help....

Personally I’d pick off all those pure yellow leaves there no use to the plant and just carry on watering until it’s ready to come down. The third one looks like it’s got 4 weeks at least left , the colouring on the leaves, I get that when temps get cooler, if it’s not your temps then not sure, could be genetics.

I removed all the yellow leaves. The ones that a light touch was enough to detach them.

Then... I don't know, it's my fist time with the magnifier and I'm worried to fuck it up.
Moreover the white widow is called "white" due to its heavy resin gland content as well as its tendency to not fully color up when ready to harvest.
IMHO the 1st and 2nd are almost ready.
What do you think?

The 3rd one is the same strain, that color is strange... they grew up in the same growbox.
