AsNoriuanswered grow question 6 months ago overdrying in soil just creates salt build up, you overfed plant, now its aftermath.
stop feeding and water with run off, plain water diet for few we/dry cycles at least.
be wise, dont do any flushes in soil, it brings more problems than sort things, its for coco or hydro.
lift pots, dont do basic mistakes as under or overwatering, have good regime .
plant will look sad and harvest will be influenced by those mistakes.
