Half of plant is dying 7th week. Grow, Partial harvest, harvest? what should I do.

I have a kush plant I have been growing for about 4 months now. I vegged slowly while I was budding another. Anyways It is in its seventh week of flowering. It was growing fine with tons of healthy leaves. I left all of them on and didnt prune for flowering. I dont know where I went wrong. I lowered one of my cfls but it wasn't that hot plus it had a fan on it. I think the air pump failed for a couple days, also I started foliar spraying with a little bit of nutes. This same spray applied to a new clone had no effects on the leaves also no effect on an established clone in veg state. Clones are of that of the plant I am posting about. The roots look brownish and as if they had rotted. I haved changed the water at the time so there was sediment as well. No ppm meter. This went from a perfectly fine plant to sickly overnight. over a course of 4 days many leaves have died and showed all types of problems such as yellowing on some, darkening on some, mottled rust on some, twisting on some, claw tips on some, Crispy dry leaves on some. Within a 12 hour dark period. Here are some picks. for some reason half of the plant is fine.

So what do I do with this thing?

Let it finish. 2 weeks and pluck that bad boy, who cares how it looks, guarantee you get some premo smoke as long as no nanners start popping out and the buds are still green and full of life, your good. If your bud starts yellowing, cut it.

2 weeks away - finish her off - wouldn't try and fix it could cause more damage than what you have. Looks like it's got enough left in her to finish with no problem.

Thanks I needed to know for sure before I got the snips out. The leaf damage doesnt touch the bud area. I am using a dwc system a gallon of straight water and I teaspoon of h2o2. Plan on just water to flush out. Good Idea to flush right? no more feeding?

Flush with distilled water

Some say Flush - Some say No. guess I use a modified version

I use RDWC and I reduce flowering nutes to 1/2 strength 3rd week out, 1/2 strength of that for the next week, then just water, a sugar supplement and some calmag for the last week while replenishing water to that as it is used until snip time. Lots of arguments on flushing or not but thats what I do - seems to work.

Flush would be good. Those ladies really look over fertilized, what was your PPM? DWC usually only requires about half strength throughout the grow. Let her finish and watch the feeding on the next group...

I just added 20oz water to the reservoir everyday as it drank or evaporated that much. I would add drops every couple days I should have just changed it out.
