What's wrong with my plant?!?

I'm very concerned about my girl. She's got discolored leaves that seem crispy. She's an autoflower on day 77 and she's in ffof being fed big bloom and tiger bloom. She's under cfls also. Can anyone diagnose her and give a solution to fix it?

Can anyone help me please

Post a pic showing more of the plant, looks like a spill to me or do you spray the leaves, wouldn't think so at this stage but just askin. Need to see more of the whole plant to formulate a better opinion

A pic of whole plant would help, but looks P or K def

I was thinking a spill, too. Deficiencies and toxicities usually have some sort of pattern, and I don't really see that here.

Pattern, lol, we only lookin at 1 leaf, but lookin at the leafs in the background, I would say this is CLEARLY no spill burn, maybe read Jorge's book

This is on many of the leaves but not all of them. They all pretty much look like that though, some worse some not so bad
