Leaves bad purple... Things were going smooth

given no other info ph,ec,run off etc i agree salt buildup has ur pots dried out all from last fert dose reverse osmosis is occuring thats y ur leaves r wilting also signs of iver fert on under growth leach with 3/4 strenght nutes little h202 to prevent over water 3%hydrogen peroxide will work as well 3% 30ml gal be lots never flush with PLAIN WATER this is a newb,expert mistake the rapid change in osmosic pressure will cause extreme damage evn deathin somecases depends on strenght was feed to plants this change is the problem even last week flower rinsce use 5%or less u will remove more salts as this solution has cations /ions (positive/neg charge) and acts as a magent to unused ferts n plants wastes

That's a good point I wish I would have thought of. I flushed with distilled and probably should have buffered it slightly. I was so concerned with disolving the salts, I didn't consider the osmotic shock. I let sit for about an hour before I refed. Hopefully, mission was accomplished without damaging the cells of the plant and roots too much.
