I notice you didn't include any pH information. If you aren't adjusting your nutrient mix to an appropriate level, around 6.9... you are asking for problems. Also, testing your runoff is important. Mystery pH can result in a wide range of health issues due to nutrient lockout. Posting additional information will help get a better idea as to what is happening.
