I noticed a little discoloration appearing on some of the leaves during last week's update. Hopefully it's all part of the bud ripening process, but I thought it was a little early for that given this strain takes 10-12 weeks flowering to finish, and it was only week 6. If not the buds ripening then it could either be nutrient burn or light burn. My COB lights can be as close as 12" but I bumped them up to 13" just in case. Several days later a flushed the medium with 4 gallons of regular water at pH 6.1 followed by a 2 gallon flush of nutrient water.
All the leaves continue to lighten in color so it is likely just what this strain is like when it finishes up. The buds are looking more like something you would smoke and the smell become more noticeable outside the closet 🙂
