So just one plant in my 3 plant dwc is showing stress. Was my light to close?
My ph is 6 and my ppm is 30. No nutes. It is one of tallest ones I have and it's the only one showing any stress

Your plant is telling you it is time to add nutes! You are noticing early signs of nitrogen shortage. Why is your rockwool black?

it just looks like the cube got too saoked and as such all that water is arresting the baby roots of all the oxygen needed to survuive. try squeezing out a little bit of the excess water in the cube and placing it so it doesnt get soaked and you should be good. Its still a seedling. DONT NUTE IT!!

They are rapid rooters. And they don't seem to soaked. I have 12 plants and it's the only one showing stress

Rapid rooters are formulated with essential nutrients. Like it or not you have already added nutes. If your Temp/Humidity are good and you haven’t overwatered then the only other logical reason for your plants stress is lack of nutes!

If you are not already using distilled water try switching over to it. Distilled water has no impurities - The impurities in your tap water could be the reason your plant is stressed. Keep in mind there is NOTHING in Distilled Water but H2O. When you start your nute program add Calcium and Magnesium to the list!

Don't add nutes it's way too small. maybe your water ph is too high. it's probably the light was too close if you think that's the most possible thing, you were there we weren't. Make sure you wait till your roots poke through the rapid rooter before you put them in the DWC. I'd keep those floros like about 3-4 inches away only because it will give your babies more coverage.

The roots have been out the bottom of the rapid rooter for 5 days.
They look smaller in the pics from above. They are 11 days old

And I am using RO water.
