At the start of this week i had to leave my plants alone for 3 days. After coming 3 days later all of the plants inside my tent were severely underwatered. I quickly watered them and now they are recovering.
One more bad news is that i found thrips in my grow tent after seeing some spots on my plants leaves.
I started spraying neem oil. I should have done that before getting infected.
I tied their branches so the canopy stays open for better light penetration.
