How soon do you need the space that it is in? If you have another plant ready to take it's place, then I say cut it and be done with it. Want to save it? Let it get dry for a couple days, up-pot it, and don't use MG with the new setup. I wouldn't use anything nutrient wise, just H2O as you may have some overkill going on in the N dept. If you do cull it, it should have effect to it. Not sure you want to smoke it if you have overloaded it with nutrients. Pay attention to the taste and how it burns. You may just want to pitch the whole thing. If you have nothing much else going at this time, it might be a decent learning experience with the up-potting thing and saving it. I am knee deep in a grow that I am wanting a do over on but I'm going to see it through. Had a heck of a harvest last run and got enough personal for a year. Had a friend of a friend close a seed shop and ended up stuffed with genetics, so I can't wait to try this one or that one, like a kid in a candy store. Time and patience are your friends.
