30 Grad im ZELT oder runter auf 60-75 Watt

I would personally take on a bit more heat and try to hit the DLI. Here's an article on DLI (I use their free app with a piece of printer paper over my camera to act as a diffuser, as instructed in the app, to measure DLI): https://growlightmeter.com/autoflowering-cannabis-lighting/ Try to play with the light intensity and light distance to your plant to get the best DLI / temp balance you can. In future grows you could also consider dropping PPFD and run the light 20 hours to hit the same DLI (I wouldn't change light hours for this grow because you're so close to the end), but here's a calculator to help: https://www.waveformlighting.com/horticulture/daily-light-integral-dli-calculator However, I would also try to mitigate the heat impact for this grow by making sure I have some fans moving air (not the plants if possible, but rather the air in the tent) and be careful about watering. If your humidity drops as temperature rises you could place a bucket of water in the tent (assuming there's enough room) and point a fan at it, the evaporating water will cool the tent slightly, but also increase humidity, so be careful with this if you try it, you don't want bud rot. If you can stay at or below 30 it would be ideal, this article talks a bit about that: growdiaries.com/journal/understanding-the-impact-of-heat-stress-on-cannabis-plants-a-crucial-challenge-for-growers But I grow in the heat outdoors, so I do grow in 32+ degrees and the plants can tolerate it, growth slows, but I would still favor light over heat, at least to 33. Looks like you'll have a solid harvest either way, congratulations, hope you enjoy it!
