Ok... I started 4 fem WW seeds 2 weeks ago. I jumped the gun a bit and fed them half strength formula after just 1 week in the DWC system. Started seeing some nute burn so I immediately change the rez to plain H20. Now it looks like the new growth is starting to get the same symptoms in plain water.
When do I start to feed seedlings in DWC? What stregnth formula? Is this nutrient burn or am i trippin.

You need those light far closer, nearly touching. I have my 250watt cfl 1'' away when im raising seedlings/vegging. As for nute burn, cant comment as the photos are too small, have you got a working airstone?

burnt for sure. 3 weeks for DWC before nutes or after the roots are a foot in length-and 1/8-1/4 to start. and u could raise that ph a bit to 5.7 5.8.

sure, they will recover. just keep checking the new growth. the plant prob sucked up the nutes before you changed and these are the effects. check the new growth to make sure it is not continuing and not a different problem. good luck with your DWC-the best way to grow-IMHO
