Ok, so I have neglected a few seedlings, because I was out of town and simply forgot about them before I left. They are in 16 oz plastic cups and have been given water and 1/4 superthrive and a small amount of Protek. They are in a combination of PromixHP and Coco. They are either leaning completely over in the cups or are starting to lean over. Can they be saved? if so what should I do? repot them in bigger pots?
