Help needed iws failed to water

Hi I need some advice my iws system failed to water my plants there 4 weeks into flower, I went into my room and they looked dead the leaves are just hanging lifeless but the plants still look green and not dried out. So I've fed them and left them for a day but nothing much as changed, will they ever recover from this will new leaves grow back will they continue to grow buds or should i just bin them ?

If you missed one feed/water, they’ll bounce back. Pics would be extremely helpful though, and you will get a lot more responses.

i went away for 5 days and pump failed. i think they are done
