How do you dose the commercial ferts you mentioned? I believe the recommended dosage is the absolute minimum amount necessary
He was to blame.............I do only dose the recommended amounts of Macro, Micro and Iron. Happy to increase this if anyone recommends that I do so.
Apologies to the bristlenose if he wasn't to blame for the holes, but he seems happy enough in his new (temporary) home at the LFS.
