Too much water? or stress from the light, young plants don't need a butt load of light. In fact, shady humid days are welcomed by plants.

Thanks for the reply buzzardbreath. They are growing hydroponically so I don't see how it can be too much water. I know they are getting plenty of oxygen.. I think you may be on to something with the light though. My ballast is dimmable so I will try turning it down to 75%

They have the classic "overwatered" look which in hydro means they are not getting enough O2. Most common reasons are root rot, insufficient bubbler, or rez temps too high (water doesn't hold O2 well when it is warm, cold water holds more). Check your water temps, good luck!

They seem to be getting more than sufficient air bubbles in the water. Also, the roots look amazing, brilliant white. Water stays about 68-70F same as the room. That's why I'm starting to lean towards a light issue, either too intense or too close. Thanks for the input :D
