Calcium def? Or something else

This is my second grow and I’m running into more issues on this one than my first grow.
Medium is FFHF (yes I know now FF soil is rubbish)
Had a nitrogen deficiency within the last week or two. And after adding some grow big the new growth was definitely more green, but i just noticed this today 0734C2FC-02DD-4095-B446-06D7CF15DF58.jpeg
Some brown spots / burns between the veins? Is this a calcium def? Or something else

I haven’t yet, after calibrating my pH meter my tap water is ~6.9 with a ppm of 138. I also didn’t filter out any chlorine / chloramines. I don’t have anything to do so at the moment. Would it be better to use distilled / purified water for feeding at this point?

Well this will help


Nitrogen deficiency is expected to show in flower, in the fan leaves or big leaves in colas.
That being said its likely hungry for little bit more of everything thing. Cal mag phos potassium. Buds appear good otherwise.

I have the NPK trio that I’ve been using at 1/2 strength since 5/16 and some cal-mag but haven’t fed the cal-mag yet. Problem with that link is I still don’t really understand what I’m looking at here
