Thanks for the tag, Evergreen. Coco is @Bill284 territory so he'll weigh in. My understanding from him is coco should never dry out but if it's straight coco it may be too heavy so adding perlite to the mix could help. Bill's got a particular mix building routine he uses to great effect.Ok just checking most time it’s over or under watering issue but maybe @Azimuth could take a look
That might be a big part of the problem here.
