Flowering Issues Week 5

Hey everyone! I am a beginner growing outdoor Green Ice Cream and OG Kush. I am now on week 6 of flowering and some of my flowers started to look like they were burning, basically, around week 5. I have given them some enzyme to help with moisture sitting in the bags, as some locked out and stopped drinking. Does anyone have any idea about what this could be? Any and all opinions welcome :slight_smile:

Thanks in advance!
