I'm the only one that would try saving them then lol. The main reason is so you find out what you did wrong. Otherwise you could well do it again.
Can I ask a few questions?
What's you medium?
How much and how often have you been watering them?
What nutes are you giving them?
Are you measuring the humidity of the tent?
What light are you using?
Are you monitoring the PH of your water?
Personally I'd waste another week trying to save them, whilst LST them. If it doesnt improve in a week then scrap them. If it does improve in 3 weeks you could be ready for flower with decent size plants.
Please note, I'm only now doing my 1st ever grow myself. However I've done 4-500hours of research before starting. But there are far more experienced growers on here. But from my perspective I'd want to work out what I did wrong.
All the best whatever you decide
