I think the coco you are using are pre-buffered, so you should be good. It is probably the really high EC in the media, it probably builds up over time which is why you have this issue later in the grow.

I'm not exactly sure how to fix it right now, besides lowering the inflow EC and irrigating more, but you also don't want to over-water since you have big pots.

In the future I would use smaller pots and irrigate more frequently with a small amount of run-off each irrigation. I don't think the inflow EC would need to be above 1.5.

What is the run-off EC since you flushed?
