Hi growers, 
I have a problem with my baby.
1 out of 5 leaves
has curled up quite a lot. It all looks like burn damage
. Because of this, I increased the distance of the 100W LED
to 45

The edges of the leaves are pointing upwards and are white at the tips, which indicates too much light. Keep an eye on the leaf tips; if they go back down, the lamp has enough distance.

Just a quick note about my leaves again.
I don’t think it was mainly just the light. But that my humidity was at approx. 58% 1-2 times for 2 hours. + a bit too much light. Could this have caused it so much?
Because I just read that for cuttings, the humidity must not drop below 60%. Because they are supposed to be too sensitive.

The humidity thing has something to do with the roots. Since these first need to grow in cuttings, the plant still absorbs water from the air until it has enough roots. It’s similar to seedlings; they also need to develop roots first. The upturned serrations of the leaves and the white tips on them are a clear sign of light that is too intense. This is still the initial stage of light burn; if you notice this on the plants, immediately raise the lamp a bit higher or turn down the dimmer a bit. When the leaves flatten out, you’ve found the right spot. It always takes a little time, but they won’t suffer any damage this way.

Ok Thanks!
With your last answer, you’ve actually almost answered my last question. Is it already too sick? And should I rather get a new cutting right away and start over? (Because the soil is still free of all additives) Or will it recover? Hope it can be clearly seen in the pictures.
I’ve raised the lamp to 50cm all day now & throttled the lamp’s minimum to 133ppfd
. But around 5 PM, I stopped watering 100ml per hour, because the soil (at least the upper part) is still too wet.

It looks like it could do with a proper dry back in the medium. Once it has dried out a bit it should perk up fairly quickly. I wouldn’t start again just yet but if you are able to get another cutting rooting there is no harm in having a backup ready to go if needed.

Thanks for the tip.
Last night, I cut off the damaged stem, hoping it would recover overnight. And that it wouldn’t waste any more energy on the broken leaf. In my opinion, it looks like it handled it well. What do you all think? I still need to pay a bit of attention to burning. I already have my light at 50cm & minimum 133 PPFD. I hope that’s enough, otherwise I’ll have to increase the distance even further.

The serrations of the leaves already look better

Hi
Regarding my water problem. The soil was too dense in the pot. Therefore, the watering water didn’t soak in properly. I have now loosened it up all around with a very fine stick (keeping a small distance from the plant). And now it’s absorbing the water properly.
Thanks again for the help !!!
p.s. If I can ever help someone, I’m happy to do so! Happy to be here!

If your humidity is too low, cut the bottom off a plastic bottle and place it over. If you remove the lid, it gets air and the humidity stays high. If the soil is

Thanks, but I don’t really have any problems with the humidity. Always between 62 - 67%.
It’s only overnight, when the humidity drops anyway, that I might need the bottle. Because my humidity drops from about 65% to about 52

Yes, of course, with me it’s the other way around right now, it always rises at night.

Okay, thanks! I’ll give it a try. I’ll let you know how it turns out.

I believe this is relevant to the topic here.

I agree with you. My humidity rises at night, not drops. Not only indoors but outside as well. I’ve never been in a position where the humidity dropped at night.
