Jacob's Remedy (Mephisto Genetics)

6/3-6/9 started getting some yellowing leaves after watering with pH'd water for about a week. possible nutrient lockout or burn, idk. probably fine to just be pHing the water regularly though, right? defoliating yellow leaves as they yellow past 30-50% of the leaf. more tips starting to curl, but otherwise looking pretty healthy, so just powering through
