GrowN'Smoke Season 8

I feel like I'm doing something wrong when it comes to the end of flowering. I've seen harvests with nice green leaves but for some reason my leaves are always yellowing and burnt by the last couple of weeks. I usually just chalk this up to harvesting time fade/fall coloring but I wonder if it's something I don't have right in my nutrients. Either way I only have about a week or 2 left of feeding, im going to implement Liquid Koolbloom the last week of feeding. The last 2 weeks of these girls I'll flush with just ph balanced water. Day 60 should be around January 8th which is my expected Harvest date so this will be my "New Year Harvest". Needless to say, I'm super excited! P.S. I added in another layer of netting to help support the really heavy buds forming. They feel super solid and thick as well as extremely sticky
