Recirculating deep water culture, issue started yesterday PH was 6.0 , I have since lowered to 5.6 to see how things adapt. Ppm 800 - jacks 321 there is some new growth that has alot less issues.

It came on quickly , I don't really understand. This isn't my first grow.

either root issue and/or nute burn led to nute lockout. even your new growth has tip burn.

Root issue if it came that quick,purple main stems says its been un healthy for awhile.
