Hi all. I'm new here and this was my first time running both dwc or floraflex. Usually a organic soil guy. I had two plants running both started to hit a wall in growth at week 5-6 during bloom. And yellowing leafs. One plant even looked a bit burned. I reduced the feed due to this, even ran them in nothing but water and drip to flush them for 24 hrs bit nothing appeared to change. Both plants were looking amazing until then. One plant was a longer cycle plant so it was 2 weeks ahead on purpose. I didn't think the second plant was going to have issues but sure did on week 5. Ph runs 5.85-6.15 but usually maintained under 6. Temps both air and water are good, no algae etc. It would appear it's nute lockout. I noticed the recommended notes were showing a higher ec than they should and reduced them but I think it was too late. I'm really confused on flushing. I figured that would work but I saw no change. I did use drip to flush in the water but nothing else. This is my first dwc or synthetic grow so I'm sure it's me but have seen many posts on other sites about nute lockout during this time. Any help would be appreciated.
