GrowMe,

Sorry to hear about the troubles. You've been through a lot in your hydro adventures. Depending on how fried they are, I would probably not just chop them down. Sometimes plants look pretty bad toward the end of flowering anyway. One of mine is almost completely yellow and brown, except for the green buds. Not sure why that is when the other plants from the same mom, in the same res are just fine. On the other hand, if there is resin they will get you high, even if you decide to harvest early. It will just be a more clear kind of high. Some pictures would help me decide what I would do, but I would be tempted to flush a couple times, let em eat a flushing agent for a day, then feed them some more and see if they perk up any.
