Plants are looking a little rough and I would love to save them. Any help would be greatly appreciated.

More than likely your soil is depleted of nutrients. Without a diary to examine and not much info to go on it’s hard to say what the problem is. But they ain’t dead yet so I’m always on team save the plant. Make sure your environment is on point and maybe feed the plant some nutrients. Some calmag and grow nutrients at a balanced PH for your soil and see what she does. She’ll either get better or die further. I think trying is better than giving up. But if you’re gonna go the route of chopping and starting over, make sure you clean your tent from top to bottom and all equipment. Your space may contain a pathogen for the plants to go like that. Anyway it’s really hard to say because of the lack of info so please don’t take what I said as Bible because I’m just giving you my best advice as to how to move forward.
