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
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!
