Thanks a lot for your response!
I have a 260W custom LED panel and it is 35 inches (91cm) away from the plant, and i can't increase the distance, cause my tent is only 63 inches (160 cm). The airflow seems ok, every hole in tent is open, extractor fan (AC Infinity) works fine i guess. But i am not really sure how to check if airflow is bad. Avg temp is 20-25C, avg hum is 45-55. And the other plant looks gigantic compared to this little one. Can it bounce back?
Thanks for helping me and my plant.
