I am growing a Jack Herrer autoflower from ILGM. The veg went great but as it went into flower i began to notice some leaves at the top of the plant turning light green
I thought it might be a sulfur deficiency so i added Epsom salts. But things have continued to get worse, and now it looks like someone spray painted light green across the tops of my plant
I have 2 plants growing under a Mars Hydro TS1000 in a 2x2 tent, the Jack Herrer and an OG Kush. Only the Jack is showing these signs. The OG shows none of this, though it could be because she is shorter. The light is a little low but still about a foot from the top of the tallest branches. I turned the light up to 100% power a few weeks ago but turned it back down to 75% a few days ago.
What do you think, is this light burn/bleaching or some other sort of nutrient deficiency?
