I agree that something is wrong. I disagree that its the light. I start veg under (3) 23 watt 6.5k CFL's and the initial stage of veg will get them to 18" before putting into the larger veg room. I also run DWC.

To hydrobro: I highly suggest filling out the form, and maybe include some pictures. Light intensity may explain the shortness, but I doubt it. I think this is a classic case of starting nutes too soon.
