OG Kush Auto

OG is getting huge but has started showing signs of potassium and phosphorus deficiencies as you can see in the photos there's some crispy leaf edges and the older leaves are starting to go pale, not in the photos but it also has purple petioles she had a feed yesterday and will get another with more pk 13-14 tomorrow so hopefully she'll bounce back soon tested the run off 6.6 pH - 630ppm
