More information will yield more assistance. From what you've said, it looks like your ec is high, possibly causing toxicity and lockout. Are you watering to runoff? What's your pH going in? RO or tap water? Could you be cooking them with light? How strong, what type, and how close are your lamps? Have you grown with this setup successfully, you mentioned prior issues with floraflex, but could it have been something else?
