@Fun_Growin, hi mate!
Thank you so much for your considerations.
I've taken some of them to be addressed:
1) interrupt watering until the plant shows some signals that it is in need (last time watering was 2 days ago, with 250ml of distilled water)
2) Lifted up the LED panel, from 50cm of distance to 100cm
I'll keep the light cycle in 20h on/ 4h off because from my recent research this is not quite a problem to auto-flowering plants, and also, so then I can change and check on thing per time, to be more accurate on my log.
Keep checking the grow, and hopefully, you will see your advice making some positive changes here!
Cheers mate
