I've also transplanted to a smaller cup since the original big pot was staying too wet for long periods of times. Let's see if i see any improvement.
Despite regular balanced feedings, she's showing deficiencies on the lower leaves. I strongly doubt that the organic BioBizz nutes are working in coco despite the addition of Acti-Vera as Biobizz suggests. I already had my doubts using organic nutes in coco but BioBizz said it's doable. It's been a big let down.
I've ordered some coco specific mineral nutrients that should be arriving soon. I'd be doing another transplant into some fresh coco to get rid of any biobizz stuff and then i'd exclusively use mineral nutrients.
