I grow several hackonechloas and they do not need rich feeding. I have them 2 metres wide in the ground but also in large containers.
for me they need moisture...in containers they need a saucer under them.
Darrenbrian, who said you need such a low ph level? Coir and bark? How long have you had them growing in this? I think you are overthinking this.
I apply a light dried manure/mpc mix over them in early spring. They grow in sun (brighter foliage) or in partial shade for me
