Deficiency or a disease?

Discussion in 'Growing Marijuana Outdoors' started by Happyfarmer123, Aug 18, 2023.

  1. Hello! So this is my critical kush, which is grown mostly in a greenhouse. It has just started to produce preflowers(seems a little late but probably ok). Recently this has appeared on the leaves-i plucked the infected ones just in case as something similar killed one of my plants before. Is it a disease or just a defficiency? I use biobizz organic nutes. Thank you

  2. Plant is hungry as it enters flowering and demand for P-K rises. Symptoms here look like Phosphorus deficiency.
