With the way the tips are clawed I would lean more towards nutrient burn or nitrogen toxicity. I would cut back on the nutrients and work your way back up. Nute burn shows up in weird ways sometimes, but the claws are a pretty good sign of too much nitrogen.

you know my crop before this experience nutrient burn and it didn't look nothing like this. my plants started to grow dark green and then the tips started to go yellow .and then start to Brown. this is like a dark gray I never seen this before.but thank u
 
it can be confusing because it does show up in different ways sometimes. if they weren’t clawed I’d totally think P or K or something other then excess N, that’s a pretty good indication for me, I could be wrong though
 
why you cut off leaves? leave em on plant, keep em on and you use em as reference if plant is getting worse or better, plant will consume nutes out of them when plant is deficient of nutes.

Best to take pics of whole plant with affected leaves still on so we can see where they are located on plant.

Did leaves come of of bottom of plant?
Whole plant pic please.... :)

I agree , I'm going thru an N deficiency and my bottom leaves were completely yellow, after feeding som veg fertilizer I've watched the lower leaves slowly turn back green it's really cool to watch
