Potassium deficiency or Nute burn ?

Sup Guys ,

Just want a second opinion , is this nute burn or potassium deficiency ?

Thanks

I would definitely say deficiency of some sort not sure which one,not nute burn though. The tips look fine. And you can see how it’s spreading on the leaves, no tacoing or curling.

Thank you I think it might be potassium which is rare in Veg I think

Hard to tell from this chart but could also be calcium def, I only have a handful of grows under my belt, but I’ve def learned about nute burn the hard way. Deficiencies are a little bit of guess and play sometimes atleast from my limited experience.

Yeah Ive been reading alot now . I think it might be because I am using tap water and that has alot of sodium in it . Which can lockout potassium
