OVERWATERING IN EBB AND FLOW

[Frazzled]

Hope you have advice or can offer assistance:

2 x 1000 mh & 1 x 1000hps
1 week in veg
flood table
water on 24/7
humidity - 35-50%
temps 25-30 degrees celcius (77F)
lights above canopy 2 feet or so
Gen HP - 900 ppm / ph 6

Problem is the plants are wilted like crazy. Dark stain on rockwool where the sprayer hits. Yellowing lower leaves. A bit blotchy on upper leaves. Some look great but most are very wilted

Are they being overwatered? How often to water?
Thanks
