It started at the bottom but very mildly almost unnoticeable. So yeah, it seems is phosphorus deficiency. Luckily, it hasn't gotten worse since adding the nutes - and most of the leaves are green, with of course, the exception of the 35% of it showing the phosphorus deficiency. Thanks for your input!Sure looks like a phosphorus deficiency to me... Did the deficiency start at the bottom of the plant and working its way up? If so definitely phosphorus with maybe a hint of potassium but to me primarily phosphorus deficiency... During flowering any yellowing of fan leaves will generally be in the last couple weeks and somewhat resemble a nitrogen deficiency normally as its a general yellowing from the plant consuming stored up nutrients shouldn't see much of any necrosis during with that type of yellowing
