Chemical nukes to organic tea.

Have pictures? Just use water for a little while and see if they look any better, check the new growth.

Switching to organics from synthetic salts\hydro nutrients is a bit tricky, you'll have these salts already built up in the soil and there is no telling how\if the microbes can rebound. Symbiotic relationships take some time to bolster.

My thoughts exactly!! AACT will help reestablish the micro herd.

Dissolving molasses in water will bind to the salts and remove them. Same deal as clearex minus an extra dollar digit.
