So your dwc. Has your Ec been going down when you check and is your ph stable when you check. If the Ec has been rising then your plants not feeding if your Ec has been dropping then it's feeding and needs a stronger dose. Like I said earlier a diary really helps spot when and what the problem was or is.

Are them leaves a bleached white colour. If so that could be the light. It would be better if you had a diary running.
