I am not very experienced grower and I can't say with certainty whats wrong with them but what I read I feel like they are just shocked from overall high nute leves in the soil. Have you checked the pH or EC of the runoff water? Might be wrong pH on top of everything or just huge stress.
My advice is to foliar feed them with water and maybe some additives (Like amino acids, vitamins, fulvic and humic acid, seaweed etc.) if you have any so they would drink the water from the leaves and not through the roots and the additives will help to bounce back from the shock faster.
