My last photo shows one of my punch drooping, I believe it's due to overwatering. I thought you couldn't really over water in coco, is it because the roots aren't receiving enough oxygen?
If your coco is wet at the same time of you asking this question then yes. The fibres do help with porosity of the medium but it still retains moisture and therefore you are not immune to overwatering. It's for this very reason many grower using coco also add perlite.
