HELP!! Nute burn?

I don’t know what’s going on. My waters ph’d and I’m using Remo nutrients (just finished week 7), terpinator, and mammoth P, and have good airflo. I thought it was a phosphorus deficiency, but it seemed to get worse, after adding mammoth P. I’m going to flush, I guess, to see if it helps at all. Any suggestion would be appreciated. I hope I can save these, and I’d sure hate to harvest early. Thanks,
