Check my grow diary. Any idea why rhe leaves on the two royal dwarfs are turning up? The blueberry zkittels look fine. They are getting about 37k lux right now. I did not start to feed the dwarfs yet. Temprature is 27 degree celcius

It's slight light stress (light is too close / too bright) Every plant reacts differently or probably PPFD at each plant is different. Just swap plants and see if it helps.

They don't look to bad to me, a slight tacho on the biggest leaves, doesn't look like it's nutrient related, could be a bit of light or heat stress.
