This is my 6th week on my autoflower grow. My plants have just started it’s transition into flowering. The strain is AK-47 XTRM auto-fem. I’ve been keeping a consistent light cycle of 20/4 and water with nutrients every 2 days. My tent is 60x60x90. I’ve noticed some flies inside my tent but don’t know what to do about them. I was wondering if anyone had any advice on how to counter the flies and yellow tips. My light is ~18-19 inches away from my plant, and is 450w.
