watering issue

Wassup everybody! I’m having some trouble with my plants and was hoping to see if someone could please help me out. I am a beginner grower and have a 4x4 grow tent with a gavita pro 1000w de. I noticed that some of my plants are looking yellow greenish. I have some pictures here if it helps...

I screw up my plants while on vacation. The automatic drip system didn’t work and plants were dried for 4 days. Is it recoverable? I was 1 week away from harvest. Looks like auger leaves r still green. Not sure if I should just chop it down or try to rehydrate. Thoughts?

Anyone have any input wether these have been overwatered or under watered these girls have been giving me a massive head ache! So these plants are 4 weeks old from Clone I transplanted them into 15ltr/3.5gal pots about 2 weeks ago I watered them in upon transplant only watering the outside...
