What is the bigger plant in the middle?

If humidity isn't a problem you could put a felt or a tissue, that is used to avoid weed on public gardens, on the bottom to suck the excessive water and let it be a moist place to the roots on the bottom of the pots. Also check if the holes on the pots are enough for the plant to breath.... Nice grow! I do suggest you an auto watering system that water up to 12 plants, it's cheap from china. It suck the water from a bucket and irrigate the plants when you program that to. Easy... As you are using hydro nutes it's perfect.
