Hey growmie, 1L a day is definitely too much for plants that size in a 30L pot , right now they only need around 400ml max every 3–4 days, watering only when the pot feels light. Topsoil can look dry, but lower down it’s still wet. Overwatering is what’s causing the droop and slow growth. Your temps and RH are fine, hygrometer is working, no problem there. For airflow, make sure your exhaust fan pulling air out is stronger than any intake, passive intake is usually enough depending on tent size. Tent walls should suck inward slightly when zipped. You’re super close, just need to water less often, maybe raise your light a bit, and tweak the airflow. Good luck growmie, hope I could help you out! 🤞🍀♥️
