Ppms are at 760 going in but what are the levels coming out?
You need to be testing ppms and pH of your return water to watch for any increase/decrease or ph swings.
Imo on the limited information you’ve provided I would say you have multiple nutrient deficiencies caused by either.
Ph fluctuation
Or under feeding.
But without all the variables that’s only a guess.
