What should i do next??!?? First time grower needs advise re flushing!!

First of all, let me start by saying that I have been sitting at the computer reading for hours, and still don't know what to do. Or maybe I know what to do - just need to know how long.
I'm a first time grower with two flowering WW's in their 8th week of flowering. They were doing great and putting on big, fat colas, when, after much reading on the subject, I finally decided to trim away some large light blocking fan leaves in Week 6. After a few days, they still looked fine and as if they hadn't suffered any stress because of the trimming. Then, when I read on RIU about Liquid Koolbloom (even though I had read it was way late in the game to start adding Liquid Koolbloom), I put about 150-200 ppm. of Koolbloom. Well, several days later, my beautiful girls' leaves are burned -droopy, dry and flimsy feeling - not like they were before. And as far as the colas go, it's like all tric production has ground to a halt.

I immediately started flushing them with plain phd water and continued to flush them for two days, after which my husband decided they were starving and that was why the colas weren't growing, so he returned the nute solution to the previous levels. Now, it's been a few days and I don't see them looking any better, worse, in fact! All this is happening at what IMHO is the most crucial time in their lives! My question for anyone with the patience to entertain it is this: How long does it take to completely flush out a nute burn, and when should we start giving them nutes again? When we do start back up with the nutes, should we include the LKB? Any advice/help would be greatly appreciated, as I feel my plants are going downhill fast and they were so beautiful! Please help!

I got my answer from the local hydro guy.

Let me guess, it involved buying some shit. Just put them back on the regular nute schedule, nothing with plants fixes itself instantly. At this point you should just try to accomadate the plant with its normal routine(pre Koolbloom) until she finishes. She might not be producing more trichomes cause she is about done and what trichomes exist are just "maturing"(ambering) at this point, hard to tell without pics. Hope you got things figured out one way or another!

Naw, Southerner, he just told me to put them on flush until I saw signs of improvement. I have been watching the trichomes, and not very many of them have heads anymore, they just look like little shards of glass. I can't see them well enough with my scopes to tell if they're clear or cloudy. But there's no amber except pistils started turning amber, right before the nute burn, about one week ago. I'm beginning to wonder if I missed something re maturity. I have been researching about the other symptoms of ripeness and looking for them. But I do think I am seeing swollen calyxes- I was looking for signs of hermying and spotted a couple of little things I thought might have been nanners which I plucked off, but haven't seen anymore since all this started. Thanks for your suggestions from a fellow Southerner!
