Hey everyone!! First time posting and also growing. I’m trying my best to identify what I have going on. I feel as if she is experiencing a magnesium or zinc deficiency and would like some expert opinions. Maybe I’m not even diagnosing correctly. What do you all think? Little background on this girl. she is an auto flower started on 3/26 in a 2.5 gallon pot of fox farm happy frog. Haven’t really given them any nutrients until yesterday. Gave 1/4 strength nutrients of fox farms bush doctor, big bloom, and tiger bloom. About a half gallon of water every 3-4 days it’s seeming like. Room temp has been around 78 during day and 68 at night. RH has been between 45-65%. I have them under a 250w blurple light set on both veg and bloom that was at a rough distance of 14 inches away. I have since backed it off to about 18-24 inches. This plant specifically is 18 inches away. I don’t assume it is light burn or bleach not sure what it is called. Anyways if anyone could help I would seriously appreciate it as I am struggling. Also a direction in where I can look for a fix would be awesome.

Magnesium is a mobile nutrient. Zinc is a immobile nutirent. Immobile you see on new growth , mobile nutrient defs start on older growth.
