Plants color looking good too, but the Kritikal-K is turning a bit violet on the edges ( on 2 leaves ).

The middle led is only 55w, I've put it there to raise a lil bit the ambient temperature.

I'm not using any nutrients for now. What do you think ?

hey there, I think you're doing great, I wouldnt add any nutes or do very many things different. What I can see is that that color change is due to temperatures not nutrient burn, so that's good news. Seems your temperatures are actually alright, so what I can see is the solution temperature you're feeding with is actually too cold. it's shocking the roots a bit and making the colors turn, so what you can do is raise the solution temperature to the optimal 21°C, and you'll be 10/10 dialed in perfectly.

Hard to tell with the light front the led. Maybe try and post a picture with out it on. But my thought would be alittle cold maybe at night when lights are off what's your day time and night time temps?. Always good to make sure theres no drafts to the babies it can shock them and sometimes not return from it or stunt them. Also doing a dome helps keep the temp and humidity up when they are that small. Well hope this helps happy growing......
