New to drip hydroponics

I think I watered them for too long and they might have bit the dust. They are still green and look ok they are just leaning pretty hard. I quit watering them like a day ago or so to dry out. I had the drip on for 24 hrs in the beginning and I think that is the problem. I was only going to do 30 min drip each day fr

om now on. Any held would be appreciated.
