Help! 4 weeks into flowering

This is my first grow and haven't really asked for help. Basically got this far with the help of google. Now I'm stumped and need some assistance so thanks in advance.
I went on vacation to south beach, Florida for 2 weeks and left my brother in law to care for the girls. I came home and this is what I had waiting...WTF (excuse the French). How to I turn this around? Is she save-able? Can I trim off those messed up ones even though she's in flowering?

* growing in fox farm soil as well as using the fox farm beginners trio
* using t5 and 6 cfl surrounding the sides
* no ph problems
* 4 weeks in flowering

Man shes very sick. What I would do is start over because even if you remove all damaged leaves, shes going to hurt trying to recover from the wounds. And as long as take for her to recover is the time you can start a fresh grow. I thought of removing all the damaged foliage and setting her back into veg. But that would be a waist of everything. Light bill, water, nutes, time and care etc.. Your brother n law is um... not cool for that trick. Very impious move he made. But it will get better... Heres a couple of ladies that Im doing right now 1 1/2 months. Sativa dom and a Indica strain im not sure of. Just some motivation to get back in the garden.

Somebody please call the cannabis police!! Them gals got abused!! There's no coming back from that much abuse. Sorry bro. Garden7 is right. Start over.

Oh man, I don't know how you'd do this with T5's but it looks like probably a lot of heat and uhh? I just...don't even, I'm so sorry for you and the gals. I came home from a camping trip to fucked up plants, haven't left for the weekend since. No one cares about your girls as much as you do, unless they do.

ouch, guys and thank for the honest responses. I'll just let her do her thing and salvage what i can and start afresh

Temps are way to high. Is that thermometer reading 90 at the dirt? Its liable to be over a 100 higher up. Are you removing the heat?
