I have no idea what it is, but i looked through the sick plant guide. my best guess is a Phosphorus deficiency? Any opinions?
Medium: Ph: nutes: Stage of life: Effected area: help me help you, looks like phosphorus right off but more info helps.
Medium: Sunshine #4 Ph: 5.8/5.9 Nutes: GH Lucas Formula Stage of Life: 20 days flowering Effected Area: Bottom fan leaf. Notes: i had a runoff of 2200ppm and a PH of 4.8 on the plant the beginning of flower, flushed twice. over 1-2 weeks. no nutes leaning towards Phosphorus due to the flush.
