Lemon AK-47

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 pulled off the dead leaves 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.
