Seedlings not improving after a week.

[Cannaman719]

I’m running blue dream, purple bubba kush, heavy grapefruit. Nutrients is drip hydro. Seedlings started off strong in rock wool cubes but once I started gently introducing them to nutrients it seems they are having a hard time. Last grow didn’t have any problems. Should I start giving them ph water to flush them out a bit? Temp is 73, humidity it 40-45%.

You should be feeding them from the top until the roots are well established in the reservoir.........they look bone dry.
Never use plain water in a dwc set up.

Jumped the gun sticking them in DWC. Damping off.

How long should I wait? Like until roots are all over the cube? What do you mean by damping off?

They have been getting fed from the top of the cube. It’s weird I did everything I did last grow, last grow was a success.

Damping off is a fungas attack. Most likely occurs with young seedlings. When kept too cold and wet. Usually results in death.

Side note, I'm pretty sure the res is supposed to be light tight, and I think I can see a sizable gap where light can get through.

I would recommend starting over and reading up on the DOs and DONTs of DWC.

Sounds good, I figured I butcher it this go around. This will be my second dwc grow. I think I just got luck last time. Has anyone used root riot cubes with success? And I will read up on the thread for DWC and see what all I have done wrong and adjust.
