When using my led at night my leaves is strait but...

LEaves will try to reduce surface area in reaction to certain stress - in this case mostly likely intensity of light. it will adapt to the sun, which might make the application of artificial light less effective. In the sun, the leaves have to adapt to handle 'too much' light. instead of a single grow light above, it's inundated by photons from all angles and not just the top of the canopy. as long as it doesn't wilt in the sun, it's probably okay. I'd wager it gets more robust as it matures and you see less of this. are you in a high DLI region of earth? There are maps, usually broken down by month of year, that can tell you a rough estimate of what 'your' sun is providing in DLI on average. These maps don't account for things like cloudy days or wheether your placement of plant get direct sun for the entire time sunrise to sunset, fwiw. more often than not, you'll fall short of these averages over time. if you are getting 35-40dli from sun consistenty, you don't even eed that grow light supplementation unless it is used to delay flowering phase of a photoperiod.

for this tiny 40k lux is enough sun's lux more then 80k+ that's the reason of curling (covering itself from to much ligh)

The Sun and your LED are very different types of light. The sun is the best and the led is like the "wish" version of the sun. Its normal behavior for leaves to curl a bit, they are adapting to the other light source. You should not be giving them to much light though overall, they need some downtime. 18/6 works great. 18hr of light and 6hrs of darkness. Plants are looking healthy so keep up the good work.

Dont ne to worried about the sun outside , ur led is to newr at the highest point from ur plant, take it on 50cm , that will be all

It's OK a little, I like to think of it similarly to being dry mouthed on a hot sunny day, she is using a little more water than she has readily available, margin tips curling up slightly is always temp related (cooling).

Das sieht mir dann doch nach Lichtstress aus, wenn mann vom Indoor sind de outdoor wechselt braucht die Pflanze etwas Zeit um sich anzupassen, ich denke das ständige hin und her wird sie noch mehr stressen. Und gerade für Autos ist der Stress nicht gut.
