Hi
@MissJokerSmoker! Sorry to hear this... In coco - or any soilless medium, you can't afford to be wrong about feedings, your diagnosis must be accurate otherwise you'll encounter more problems than you initially had. Now that you gave her too much P while this wasn't necessary, your rootzone must be really disturbed. I would recommend to keep on flushing because you're getting close to harvest and at this stage there's not much you can do. In this scenario I would remove the most affected leaves, flush the medium with plain pH'd water (~5.8) and see how it goes after a few days. Hope this will help, keep us up-to-date and happy growing 👊
